specific distribution. The Kolmogorov-Smirnov (K-S) test is based on the empirical distribution function (ECDF). Given N ordereddata points Y1‚ Y2‚ ...‚ YN‚ the ECDF is defined as \[ E_{N} = n(i)/N \] where n(i) is the number of points less than Yi and the Yiare ordered from smallest to largest value. This is a step function that increases by 1/N at the value of each ordered data point. The graph below is a plot of the empirical distribution function with a normal cumulative distribution function
