Parallel Computing is a compelling imaginative and prescient of ways computation can seamlessly scale from a unmarried processor to almost unlimited computing strength. regrettably, the scaling of software functionality has no longer matched top pace, and the programming burden for those machines continues to be heavy. The functions needs to be programmed to take advantage of parallelism within the best manner attainable.

If we use an estimator Evaluation of the performance of survival analysis models 11 of β obtained based on the grouped observations such as the minimum modified chisquare estimator, then the estimated χ 2 ( β ) has asymptotic χ 2 (M − k) distribution. In most cases in practice, however χ 2 ( β ) is estimated by substituting the maximum ˆ which is based on the ungrouped observations. 22), K =χ 2 2 βˆ = M [ Wi − i∈Ij ˆ i∈Ij H0 (ti )eβvi ]2 ˆ j =1 i∈Ij H0 (ti )eβvi . 23) ˆ even though the data are grouped into M cells, the expected In the K 2 statistic with β, cell frequencies are obtained based on the original observations.

3) i=1 where ψi is a score associated with the ith ordered X. Since our data is ordered by increasing X, if we set γ equal to the [np]th smallest X we have that [np] γ Uβ (p) = ψi . 5) converges weakly to W , a Brownian Motion process on the unit interval, when v = (E[ψi2 ])1/2 . Wu (2001) shows that for the Weibull, exponential, log logistic and log normal models, the ψi ’s have mean zero and v can be estimated consistently by ψi2 /n. In these cases S(p) = [np] i=1 ψi n 2 i=1 ψi . 12). The value of p which maximizes |S(p)| gives the estimate of γ equal to the [np]th smallest of the X’s.

N are exchangeable random variables that meet the following three conditions: n n ϕi → 0, i=1 ϕi2 → 1 p i=1 p and max |ϕi | → 0 1 i n p as n → ∞. 14) i=1 where [ ] is the greatest integer function. When there is no censoring so that n = D, one can show that the log rank test is precisely equal to Savage’s test which is a linear rank test with exponential scores for the ith smallest death time given by i ai = 1 − j =1 1 . 16) i=1 where X(i) is the value of X associated with the ith smallest death time.
