From Wikipedia, the free encyclopedia

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)
