# Calculating the Kolmogorov-Smirnov coefficient

I need to calculate the coefficient of the Kolmogorov-Smirnov test for any given null hypothesis rejection level.

For example, have a look at the table in this wikipedia entry. It only gives $c(\alpha)$ for $\alpha=0.10, 0.05, 0.025, 0.01, 0.005, 0.001$. How can I calculate $c(\alpha)$ for a wider range of $\alpha$s?

If it is not trivial, can any one guide me on a place I can find a table for $c(\alpha)$ with larger $\alpha$ values?

• An alternative (and more easily accessible) link to the original paper should be here. Note that the tables given there are quite extensive. The $L(z)$ values correspond to $(1-\alpha)$ and the $z$ to $c(\alpha)$. – Glen_b Nov 5 '13 at 11:17
I found this paper (Marsaglia, et al. (2003)), that has a method to approximate the probability of obtaining a certain $D_n$ for a certain number of data. It Also has a C program that I used in my program and worked excellently.
