5.3: Mean and Standard Deviation of Binomial Distribution

WebbSampling, Populations, and The Standard Error of the Mean Binomial Theorem Let's get started by reminding ourselves of what we learned last class: The binomial distribution. Given some success parameter \ (p\), the binomial distribution lets us ask: what is the probability that in my sample of n trials I observe k successess? When n is known, the parameter p can be estimated using the proportion of successes: This estimator is found using maximum likelihood estimator and also the method of moments. This estimator is unbiased and uniformly with minimum variance, proven using Lehmann–Scheffé theorem, since it is based on a minimal sufficient and complete statistic (i.e.: x). It is also consistent both in probability and in MSE.

WebbIt is the standard deviation of the expected error. This expression should be valid for all binomial distributions. In practice, if the probability is quite close to one or to zero while you have few samples, the value given by the expression might have large error. Make sure your sample sizes are large enough. – EngrStudent Jun 29, 2015 at 17:59 WebbB.4 Binomial Errors and Link Logit.
