Probability from different distrubution

[From: ] [author: ] [Date: 12-04-12] [Hit: ]
so,my question is, what can i say about probability of event i in overall experiment?-P_i is not the probability of event i. It is the estimate of the probability.If you have more than one experiment,......
Hi,

suppose you collect data from an experiment and calculate P_i of event i.
you repeat the experiment and again determine the probability of event i .
(can not change the size of sampling in each experiment. so, suppose every time we have 100 samples)
my question is, what can i say about probability of "event i" in overall experiment?

P_i is not the probability of event i. It is the estimate of the probability.
If you have more than one experiment, say m experiments with the following data:
for experiment 1 you get (E1,n1) with P_i = E1/n1, for experiment 2 you get E2/n2 ...etc
Then, the overall estimate P_i = (E1 +E2 +...+ Em)/n1+n2+...nm).
So, as you see, you may have different sample sizes for the various experiments.
