How does the Kolmogorov Smirnov Calculator work?

Test statistic D = max|Fn(x) - F(x)| (empirical vs. theoretical) Then: Or D = max|F1(x) - F2(x)| (two samples) Then: Null hypothesis: distributions equal Then: Non-parametric; no distribution assumptions.

Can you give an example of how to use the Kolmogorov Smirnov Calculator?

Example: Input Sample vs CDF gives a result of KS statistic.
