The PROBT function returns
the probability that an observation from a Student's t distribution, with degrees of freedom df and noncentrality parameter nc, is less than or equal to x. This function accepts a noninteger degree
of freedom parameter df. If
the optional parameter, nc,
is not specified or has the value 0, the value that is returned is
from the central Student's t distribution.
