Empirically, the three factors are found to have a small correlation among them. Actually, it is possible to arrive to these factors supporting the analysis on principal component analysis or assuming zero correlations between them.

Figure 5 NSS System This system will be overidentified, which means that there are more knows than unknowns, and it is necessary to minimize a norm of the residuals.

A result from the numerical analysis is that the size of the minimized residual is not necessarily influenced by the conditioning of the equations.

Researches have been aware of a certain potential multicollinearity issues while estimating the NS model making difficult to estimate the parameters correctly.

It is interesting to highlight that the correlation between two regressors of the model depends on the time to maturity of the financial instruments chosen.

The problem is that for many values of lambda, the factors are highly correlated and we find that the system is badly conditioned. The correlation also depends of the time of maturity and those series of short maturities turns out to be the most sensitive to the collinearity issue.

We can see that the maturity choice influences the steepness of the correlation curve. In the NSS-case we can observe the most obvious case. The correlation is 1 at lambda equals to 0, and rapidly decays to The interesting range is between lambda equals to 0.

The collinearity is not necessary a problem in forecasting as we can measure their combined effect. The problem is when we want to predict the regression coefficients themselves.

A well-chosen lambda should result in non-correlated coefficients. But, in case of fixing a highest lambda as needed, the result will be time series for each coefficient with strong correlations and the series will present much more volatile.

A high multicollinearity among regressors can also inflate the variance of the estimators, so that more difficult to model. In conclusion, it would be useful to restrict the lambda values where practical identification is still possible.

The VIF is defined as: The tolerance level is the reciprocal of VIF. First of all, we consider here data for a selected day as given in table Treasury Market Association in China We have exclude one bond with less than three months to maturity, because the yields on these securities often seem to behave oddly and the bonds with more than ten years to maturity has been difficult to find all information related to compute properly our following estimation.

Now, with the set of data described above we performed a numerical experiment using an excel formula to compute the NSS model, and the solver formula to minimize the distance between the observed yield curve and the theoretical yield curve, changing the parameters from the model, in order to get the estimation of them.

So our method has been the optimisation method minimizing the residuals from the observed curve from our NSS model formula using 3 , applied to excel The estimated spot rate for the bond with maturity within one year is 2.

Now we are able to know infinite yields for maturities between 0 years and 9 years, whereas without the estimation provided for NSS-model we was able to know only the observed yields in the market for a given maturity in the market.

We can observe that the unknown data has been obtained pretty well, so that our model allows us to know what is the yield for a given maturity in a specific market without making additional computations.

And also not always are available all data from each security per each maturity, so here the estimation also it is very helpful.

In practice the model is calculed by the optimitation problem shown in equation 3. The mean problem of the model is the multicollinearity, where several parameters explain at the same time the same information.

The correlation between two regressors of the model depends on the time to maturity of the financial instruments chosen.

This system will be overidentified, which means that there are more knows than unknowns. Finally, calibrating our numerical example we had used the optimisation method because is the most practical one.

We can conclude that Nelson-Siegel-Svensson model is a good model to replicate the behaviour of the yield curve of chinese government bonds.

Once we have done this work, we are aware that this is a really powerful method to deal with the yield curve that it is really useful to both researchers and financial participants in the market, thereby helping to make the decisions with more information.

The Nelder—Mead method requires, in the original variant, no more than two evaluations per iteration except for the shrink operation described later, which is attractive compared to some other direct-search optimization methods.

However, the overall number of iterations to proposed optimum may be high. It then extrapolates the behavior of the objective function measured at each test point, in order to find a new test point and to replace one of the old test points with the new one, and so the technique progresses.

The simplest approach is to replace the worst point with a point reflected through the centroid of the remaining n points. If this point is better than the best current point, then we can try stretching exponentially out along this line.

An intuitive explanation of the algorithm is presented in: These steps are called reflections, and they are constructed to conserve the volume of the simplex and hence maintain its nondegeneracy.

When it can do so, the method expands the simplex in one or another direction to take larger steps. Unlike modern optimization methods, the Nelder—Mead heuristic can converge to a non-stationary point unless the problem satisfies stronger conditions than are necessary for modern methods.

Many variations exist depending on the actual nature of the problem being solved. A common variant uses a constant-size, small simplex that roughly follows the gradient direction which gives steepest descent.

Visualize a small triangle on an elevation map flip-flopping its way down a valley to a local bottom. This method is also known as the Flexible Polyhedron Method.

This, however, tends to perform poorly against the method described in this article? In that case we contract towards the lowest point in the expectation of finding a simpler landscape.

However, Nash notes that finite-precision arithmetic can sometimes fail to actually shrink the simplex, and implemented a check that the size is actually reduced.

The initial simplex is important. Indeed, a too small initial simplex can lead to a local search, consequently the NM can get more easily stuck.

In most multicellular eukaryotic organisms, telomerase is active only in germ cells , some types of stem cells such as embryonic stem cells , and certain white blood cells.

Telomerase can be reactivated and telomeres reset back to an embryonic state by somatic cell nuclear transfer.

Telomere length varies greatly between species, from approximately base pairs in yeast [25] to many kilobases in humans, and usually is composed of arrays of guanine -rich, six- to eight-base-pair-long repeats.

Multiple proteins binding single- and double-stranded telomere DNA have been identified. Telomeres form large loop structures called telomere loops, or T-loops.

Here, the single-stranded DNA curls around in a long circle, stabilized by telomere-binding proteins. This triple-stranded structure is called a displacement loop or D-loop.

Telomere shortening in humans can induce replicative senescence, which blocks cell division. This mechanism appears to prevent genomic instability and development of cancer in human aged cells by limiting the number of cell divisions.

However, shortened telomeres impair immune function that might also increase cancer susceptibility. Uncapped telomeres also result in chromosomal fusions.

Since this damage cannot be repaired in normal somatic cells, the cell may even go into apoptosis. Many aging-related diseases are linked to shortened telomeres.

Organs deteriorate as more and more of their cells die off or enter cellular senescence. At the very distal end of the telomere is a base pair single-stranded portion, which forms the T-loop.

This loop is analogous to a knot, which stabilizes the telomere, preventing the telomere ends from being recognized as break points by the DNA repair machinery.

Should non-homologous end joining occur at the telomeric ends, chromosomal fusion will result. Telomeres shorten in part because of the end replication problem that is exhibited during DNA replication in eukaryotes only.

However, there is a problem going in the other direction on the lagging strand. To counter this, short sequences of RNA acting as primers attach to the lagging strand a short distance ahead of where the initiation site was.

The DNA polymerase can start replication at that point and go to the end of the initiation site. This causes the formation of Okazaki fragments.

This happens at all the sites of the lagging strand, but it does not happen at the end where the last RNA primer is attached. However, test-tube studies have shown that telomeres are highly susceptible to oxidative stress.

There is evidence that oxidative stress-mediated DNA damage is an important determinant of telomere shortening. Population-based studies have also indicated an interaction between anti-oxidant intake and telomere length.

Telomere shortening is associated with aging, mortality and aging-related diseases. Normal aging is associated with telomere shortening in both humans and mice, and studies on genetically modified animal models suggest causal links between telomere erosion and aging [33].

However, it is not known whether short telomeres are just a sign of cellular age or actually contribute to the aging process themselves.

Although leukocyte telomeres shorten with age, sperm telomeres lengthen with age. A meta-analysis of 23 studies found that increased perceived psychological stress was associated with a very small decrease in telomere length — although there was also evidence of potential publication bias, which when taken into account attenuated this effect and made it non-significant.

The phenomenon of limited cellular division was first observed by Leonard Hayflick , and is now referred to as the Hayflick limit.

West that tied telomere shortening with the Hayflick limit. Telomerase was demonstrated in a publication in Science to be capable of extending cell lifespan, and now is well-recognized as capable of immortalizing human somatic cells.

It is becoming apparent that reversing shortening of telomeres through temporary activation of telomerase may be a potent means to slow aging.

The reason that this would extend human life is because it would extend the Hayflick limit. Three routes have been proposed to reverse telomere shortening: So far these ideas have not been proven in humans, but it has been demonstrated that telomere shortening is reversed in hibernation and aging is slowed Turbill, et al.

In conclusion, it would be useful to restrict the lambda values where practical identification is still possible. The VIF is defined as: The tolerance level is the reciprocal of VIF.
