Generic goodness of fit tests for random plain old data. Goftests is intended for unit testing random samplers that generate arbitrary plain-old-data, and focuses on robustness rather than statistical efficiency. In contrast toscipy.statsandstatsmodels, goftests does not make assumptions on the dist...
In a steady-state simulation, the initial conditions often bias the estimators, sometimes severely. A common method for ameliorating this is to delete an initial portion of the run, perhaps entailing substantial data loss. We investigate feasible methods for initializing such simulations that lead to...
通常情况是进行多次初始化(一般是50-1000次),然后在这些结果中选择一个最好的(即cost function的值最小的那个聚类) 这种通过多次初始化来选择较好的局部最优解(或者全局最优解)的方法适用于K较小(即聚类的个数)为2-10(特别是K=2,3,4,5,6)的情况;如果K很大,则多次初始化选择出来的最优解可能与第一次初...
Similar to Shuffleable, except no element is ever in its initial position. Swift Types Integers All of Swift's native integer types conform to the Random- protocols. The random(using:) function creates an integer of any value. As a result, negative values can result for signed integers. Int...
The maximum bias for a compounded set can be very small (even when the maximum bias for the initial set is quite large) but has a lower bound depending on the bias contribution from dependence among rows. One approach is oriented toward minimizing m for a given maximum bias for the ...

Nevertheless, one can clearly observe the randomness of the data as the figure is indistinguishable from noise. Then a randomly selected 5 Gbits of the entire generated random bit sequence is fed to the NIST randomness statistical test suite, a well-known benchmark for statistically certifying the...
The training options were the following: initial lambda (0.0000005), initial sigma (0.00005), interval center (0), interval offset (±0.5) The gene expression data of follicular lymphoma corresponded to the publicly available GSE16131 dataset (Affymetrix GPL96/97, HG-U133A/B; Affymetrix Inc.,...
