Hello everyone,

I have the following data (attachment) and I want to evaluate if they are

distributed according to Poisson statistics. To do this, I performed the

following script

A=load("output.txt");

[frec,xx]=hist(A);

N=sum(frec);

frec_rel=frec/N;

mu_pond=sum(xx.*frec_rel)

x=[0:1:300];

p=poisspdf(x,mu_pond);

bar(xx,frec_rel)

hold on

plot(x,p, "LineWidth",5)

The result that I get from the density function is very different from that

obtained from the relative frequency. Could someone explain to me why such a

difference?

As I understand it, from the weighted average and using the poisspdf

function I should get something similar to the relative frequency

regards
