[R] qcc.overdispersion-test

Hi all,

I have made an overdispersion test for a data set and get the following result

Overdispersion test Obs.Var/Theor.Var Statistic p-value
        poisson data          16.24267  47444.85       0


after deleting the outliers from the data set I get the following result


Overdispersion test Obs.Var/Theor.Var Statistic p-value
        poisson data          16.27106         0       1


The problem is that the overdispersion parameter does not really  
change, but how could the p-value and the statistic change so that the  
null hypothesis is accepted??

I would be very grateful if someone could help me?
