In the left-hand tail, , if the safe range parameter (x02am), then is returned, which is close to the true value.
The relative accuracy is bounded by the effective machine precision. See s15ag for further discussion.
If, before entry, is not a standard Normal variable, it has to be standardized, and on exit, g01mb has to be divided by the standard deviation. That is, if the Normal distribution has mean and variance , then its hazard rate, , is given by
The hazard rate is evaluated at different values of for Normal distributions with different means and variances. The results are then printed.
