SYNOPSIS
SUBROUTINE RETAIN(X,N,Xmin,Xmax,Newn)
DESCRIPTION
RETAIN(3f) retains all observations in the REAL vector X which are inside the closed (inclusive) interval defined by XMIN and XMAX, while deleting all observations outside of this interval.Thus all observations in X which are smaller than XMIN or larger than XMAX are deleted from X. RETAIN(3f) (and the REPLAC and DELETE subroutines) gives the data analyst the ability to easily ’clean up’ a data set which has missing and/or outlying observations so that a more appropriate subsequent data analysis may be performed. For example, a trimmed sample can easily be constructed by use of RETAIN(3f).
