Description (last modified by liukis)

Global one-year experiments were displaying weird plots for T and W tests results as of 2012/10/25. Debugging the problem showed that forecasts are providing zero rates for some observed events that resulted in -inf/inf values after np.log(0).

Should replace zero rates with Nan value for the test
