shouldn't the graph's x-axis be in percentile and not in probability? The range of CDF is percentile (0,1) = (0th percentile, 100th percentile), whereas the range of normal distribution is probability (0,1) = (0%,100%). Since the probit is the CDF inverse, it's domain is CDF's range, which is in percentile, not probability. Thoreaulylazy 15:23, 3 October 2006 (UTC)[reply]

In addition, the probit transformation should add 5 to the resultant values so that there are no negative values. —Preceding unsigned comment added by 159.247.2.7 (talk) 13:32, 20 June 2008 (UTC)[reply]
