Provided a standard sequence of n independent Bernoulli trials in which the probability of success is θ and the probability of failure is 1−θ.
If A represents the observed number of success and B represents the observed number of failures, (with A+B = n), then find I(θ), the Fisher information matrix. (Hint: Recall that the sum of n Bernoulli trials is a Binomial random variable. Also assume that n, A and B are fixed and so the only unknown parameter is θ, in the case I(θ) will be a scalar.)

Negative Binomial experiment is based on sequences of Bernoulli
trials with probability of success p. Let x+m be the number of
trials to achieve m successes, and then x has a negative binomial
distribution. In summary, negative binomial distribution has the
following properties
Each trial can result in just two possible outcomes. One is
called a success and the other is called a failure.

Independent trials, each of which is a success with probability
p, are successively performed. Let X denote the first trial
resulting in a success. That is, X will equal k if the first k −1
trials are all failures and the kth a success. X is called a
Geometric random variable (google it). Determine the moment
generating function of X.

sigma. ?Also, use the range rule of thumb to find the minimum usual
