judge if the data obeys poisson distribution
parameter, the number of successful events in unit time.
Given a set of observations from a certain distribution, this function is used to test whether the observations are from a distribution of possion distribution or not. Usually, to ensure the function works well, the sample size needs to be large enough, i.e. the result will be stable if the sample size is larger than 100.
if the data possibly obeys poisson distribution, return a value named qchisq which represents the possibility. The larger qchisq is, the larger the possibility will be; else return -1.
please pay attention to the definition of parameters in our functions.
