Suppose now How to find the mle (maximum likelihood estimate) of p, based on the whole sample.

I would think that these are i.i.d. Bernoulli's.

Let for i=1,2,...,n.

Here isn't really the point

The MLE of Bernoullis is the sample mean of the Y's.

Since the Likelihood function is

Now take the log and differentiate TWICE and obtain the sample mean as the MLE. - Nov 19th 2009, 11:03 PMnoob mathematician
Given the Y_i defined by u:

Let say now I want to know the MLE of p(1-p), is it right for me to conclude that it is ? - Nov 19th 2009, 11:12 PMmatheagle
I believe that is correct under the invariance principle of MLEs.
