invNorm(
computes the inverse cumulative normal distribution function for a given
area
under the normal distribution curve specified by mean
m and standard deviation s. It
calculates the
x
value associated with an
area
to the left of the
x
value. 0
area
1 must
be true. The defaults are
m=0 and s=1.

computes the inverse cumulative Student-t probability function specified by Degree
of Freedom, df for a given Area under the curve.
