Title

    rtnorm() -- Truncated normal pseudorandom variates.


Syntax

        real matrix   rtnorm(real scalar r, real scalar c,real rowvector
                              m,real rowvector s,
                              real rowvector lower, real rowvector upper)



Description

    rtnorm(r,c, m, s, lower, upper) returns an r x cj real matrix containing
    truncated normal random variates. The real-valued rowvectors m and s
    contain the mean and standard deviation parameters before truncation,
    respectively.  The real-valued rowvectors lower and upper contain
    parameters defining the two-sided truncation of the distribution.  The
    matrices m,s,lower and upper must be c-conformable.


Conformability

        rtnorm(r,c, m, s, lower, upper):
                r:  1 x 1
                c:  1 x 1
                m:  1 x 1 or 1 x j
                s:  1 x 1 or 1 x j
            lower:  1 x 1 or 1 x j
            upper:  1 x 1 or 1 x j
           result:  r x c or r x cj 


Diagnostics

        
    The random-variate generator abort with error if r<=0 or c<=0.

        
    rtnorm(r,c, m, s, lower, upper) abort with an error if the parameter
    rowvectors do not conform.  See c-conformable for rules on matrix
    conformability.
