Detailed Description

calculates loglikelihood ratio statistics

This function needs an expected histogram in addition to the observed histogram.

The statistics is $\sum^{k}_{i=1}x_{i}\log(x_{i}/n\pi_{0i}$

where $x_{i]$ is the observed frequency of the $i$ th bin, and $n\pi_{0i}$ is the expected frequency.
