#' A repeated epi.tests function
|
|
#'
|
|
#' Repeats the epi.tests from the epiR package. Either gs or test should be of length 1.
|
|
#' @description For bivariate analyses. The confint() function is rather slow, causing the whole function to hang when including many predictors and calculating the ORs with CI.
|
|
#' @param gold the test or meassure used as "golden standard". Format as list of variable names to include. All variables should be formated as dichotomised factor.
|
|
#' @param test possible predictive tests to evaluate. Format as list of variable names to include. All variables should be formated as dichotomised factor.
|
|
#' @param data dataframe to draw variables from.
|
|
#' @keywords ppv npv sensitivity specificity
|
|
#' @export
