with the current pst-math.pro (loaded by package pst-math) you can
write

\documentclass[a4paper]{article}

\usepackage{pst-plot,pst-math}

\begin{document}

\psset{xunit=5}
\begin{pspicture}(0,-3)(1,4)
\psaxes{->}(0,0)(0,-3)(1,4)
\psplot[plotpoints=200,algebraic,linecolor=red]{0}{0.9999}{norminv(x)}
\psplot[plotpoints=200,algebraic,linecolor=blue]{0}{0.9999}{vasicek(x)}
\end{pspicture}

\end{document}

and get the attached.
