xactonomial: Exact Inference for Real-Valued Functionals of k-Sample Multinomial Parameters
We consider the k sample multinomial problem where we observe k vectors (possibly of different lengths), each representing an independent sample from a multinomial. For a given function psi which takes in the concatenated vector of multinomial probabilities and outputs a real number, we are interested in constructing a confidence interval for psi. We use an exact (but computational and stochastic) method to compute a confidence interval and a function for calculation of p values. The details of the method will be in a forthcoming preprint.
