... An example is Wilson’s method, the default of the R command binconf. We do not treat the theoretical backgrounds here but compare its results to the Wald method. Remember: Confidence intervals are random because they depend on the data. Theoretically, a method for generating 95% confidence intervals ...

Recall the properties of a Binomial Distribution: X = number of success and X ~ Bin(n, p) then • n = number of trials • X = number of success out of n trials • p = probability of success but we can also think of this as the population portion of successes • q = probability of failure or the populati ...

German tank problem
In the statistical theory of estimation, the problem of estimating the maximum of a discrete uniform distribution from sampling without replacement is known in English as the German tank problem, due to its application in World War II to the estimation of the number of German tanks.The analyses illustrate the difference between frequentist inference and Bayesian inference.Estimating the population maximum based on a single sample yields divergent results, while the estimation based on multiple samples is an instructive practical estimation question whose answer is simple but not obvious.
