PsiSlurp returns trials for an uncertain variable from a table of correlated sample data, called a Stochastic Library Unit, Relationships Preserved (SLURP), in the sequence specified in the table. The slurp argument is a rectangular Excel cell range containing the SLURP data; the j argument is the index of the desired SIP (column) of the SLURP, starting from 1. The value returned by PsiSlurp() on the ith trial is taken from the ith row and the jth column of the table. Use PsiCertify() in the 2nd argument to certify the SLURP. See the PsiCertify property for more information on certifying a distribution.
