SWTEST Shapiro-Wilk parametric hypothesis test of composite normality.

[H, pValue, SWstatistic] = SWTEST(X, ALPHA, TAIL) performs

the Shapiro-Wilk test to determine if the null hypothesis of

composite normality is a reasonable assumption regarding the

population distribution of a random sample X. The desired significance

level, ALPHA, is an optional scalar input (default = 0.05).

TAIL indicates the type of test (default = 1).-SWTEST Shapiro-Wilk parametric hypothesis test of composite normality.
