- 14:54, 12 January 2007 Coffee2theorems talk contribs uploaded File:Probit plot.png (Updated the plot by omitting axis labels because the article is about the probit function, whose definition as such does not include units. The plot in article on logit does not have any labels either.)
- 13:43, 23 July 2006 Coffee2theorems talk contribs uploaded File:Probit plot.png (Plot of the probit function <math>\sqrt{2}\,\operatorname{erf}^{-1}(2p-1)</math>. I created this image myself with the following Python code: <pre> from matplotlib.pylab import * from scipy.special import erfinv def probit(p): return sqrt(2)*erfinv(2*p-1)
