T_alpha {skedastic}R Documentation

Pseudorandom numbers from Asymptotic Null Distribution of Test Statistic for Method of Rackauskas and Zuokas (2007)

Description

A matrix of 2 ^ 14 rows and 16 columns. Each column contains 2 ^ 14 Monte Carlo replicates from the distribution of T_{\alpha} for a particular value of \alpha, \alpha=i/32, i=0,1,\ldots,15. The values were generated by first generating a Brownian Bridge using m = 2 ^ 17 standard normal variates and then applying Equation (11) from Rackauskas and Zuokas (2007). It can be used to compute empirical approximate p-values for implementation of the Rackauskas-Zuokas Test for heteroskedasticity. This is a time-saving measure because, while rackauskas_zuokas contains an option for simulating the p-value directly, this would be computationally intensive for the authors' recommended m of 2 ^ 17. Passing the argument pvalmethod = "data" to rackauskas_zuokas instructs the function to use the pre-generated values in this data set to compute the empirical approximate p-value for the test.
