(Cumulative Distribution Function) Useful when used in conjunction with probability scales. If x is the number of standard deviations a measurement departs from the mean, then the associated probability (0-100) is:

cdf(x) will plot as a straight line on a probability scale.

cdf((x-<mean>)/sqrt(<stdev>)) will give the cumulative distribution function for a series with mean value=<mean> and standard deviation <stdev>.
