SYNOPSIS

SUBROUTINE SCALE(X,N)

DESCRIPTION

scale(3f) computes 4 estimates of the scale (variation, scatter, dispersion) of the data in the input vector x.

the 4 estimators employed are--

1.	the sample range;
2.	the sample standard deviation;
3.	the sample relative standard deviation; and
4.	the sample variance.

note that n-1 (rather than n) is used in the divisor in the computation of the sample standard deviation, the sample relative standard deviation, and the sample variance.
