Documented in predict_model

#' @title predict_model
#' @description calibrates the uncalibrated predictions \code{new} using \code{calibration_model}.
#' @param new vector of uncalibrated predictions
#' @param calibration_model calibration model to be used for the calibration. Can be the output of \code{\link{build_BBQ}},\code{\link{build_hist_binning}} or \code{\link{build_GUESS}}.
#' @param min minimum value of the original data set
#' @param max maximum value of the original data set
#' @param mean mean value of the original data set
#' @param inputtype specify if the model was build on original (=0), scaled(=1) or transformed (=2) data
#' @return vector of calibrated predictions
#' @rdname predict_model
