Abstract: halfnormden computes the half-normal density distribution function, halfinvnorm computes the inverse cumulative standard half-normal distribution function, and halfnorm computes the cumulative standard half-normal distribution. The half-normal distribution is a Normal distribution truncated to only have a nonzero density for values to the right of the peak. In the half-normal distribution, the parameter theta is related to the standard deviation (sd) of the corresponding normal distribution by the equation theta = sqrt(pi/2)/sd. The default theta is sqrt(pi/2) which corresponds to sd = 1. halfnormdeni, halfinvnormi and halfnormi are the immediate forms of halfnormden, invnorm and normd, respectively; see immed.
