Plot of the probit function . I created this image myself with the following Python code:

Category:Images with Python source code 
from matplotlib.pylab import *
from scipy.special import erfinv


def probit(p):
    return sqrt(2) * erfinv(2 * p - 1)


x_i = arange(0.0001, 0.9999, 0.001)
plot(x_i, probit(x_i), 'r')
xlabel('probability')
ylabel('probit')
grid(True)
xticks(arange(0, 11) / 10.0)
savefig('image.png', dpi=80)
