The empirical cumulative distribution function (ECDF for short) calculates
the fraction of observations less or equal to a given value. The resulting
plot is a step function of that fraction at each observation. This function
uses ecdf
and overlays the CDF for a fitted normal function as well.
Inspired by a chart in Ruppert (2004).
