Thus we conclude that Null Hypothesis H0 that NUMBIDS is Poisson distributed can be resolutely REJECTED at 95% (indeed even at 9.99%) confidence level.
WebThe resulting value can be compared with a chi-square distribution to determine the goodness of fit. The chi-square distribution has ( k − c ) degrees of freedom , where k is the number of non-empty cells and c is the number of estimated parameters (including location and scale parameters and shape parameters) for the distribution plus one.
