#' Calculate multiple simultaneous confidence intervals using selected methods (excluding Bayesian methods)
#'
#' Return simultaneous confidence intervals for multinomial proportions based on selected methods.
#'
#' @md
#' @param inpmat the cell counts of given contingency tables corresponding to categorical data
#' @param alpha a number in `[0..1]` to get the upper 100(1-`alpha`) percentage point of the chi square distribution
#' @param methods character vector of one or more methods to run over the input parameters
#' @return `tibble` with original and adjusted limits of multinomial proportions together with
#' product of length of k intervals as volume of simultaneous confidence intervals.
#' The `inputmat` and `alpha` values are also returned in the `tibble`.
