Dear S-list readers: Royston described the effect of sample size on the p-value obtained from the Shapiro-Francia test (Estimating departure from normality. Stat Med 1991;10:1283-93). He developed two indices from the Shapiro-Francia test (i) V' - an index of departure from normality and (ii) v' - a plot of the cumulative squared residuals. He mentioned the availability (in 1991) of a Minitab macro and a Stata program for calculating V' and producing v' plots. Unfortunately he no longer has these scripts in his computer. Therefore I wondered if any reader of this list possessed S (or indeed R) versions of Royston's routines? I have, of course, done the usual searches but only obtain references to Royston's own modifications of the Shapiro-Francia test itself. Any help or advice would be gratefully received. Thank you.
