Cell Transformation Assay: How to calculate the Poisson ratio?

10 October 2012 0 4K Report

Could anyone help me finding a software able to calculate the Poisson ratio between two different event distribution (control group vs treatment) in order to evaluate if the event frequency is statistically different? I would prefer free software but we have also PRISM, STATISTICA, STATA e SAS but, i think, they are not able to calculate the above mentioned parameters.
