'ATKPLOT': module to generate Atkinson residual normality plots
DESCRIPTION/AUTHOR(S)
atkplot graphs the half-normal plots with the confidence bands
for regression residuals as suggested by Atkinson (1985) and
described in Smith and Young (2001). This is a graphical tool to
assess the normality of the residuals. For this purpose, absolute
values of the residuals are ordered and plotted against the
expected order statistics of the (half-)normal distribution. The
k-th percentile of interest is calculated using Blom (1958)
approximation (k-3/8)/(N+1/4), where N is the total number of
observations. The confidence bands for the residuals are obtained
via simulation with the normal errors. No Bonferroni or any other
simultaneity correction is made.
