#' Stackloss data
#'
#' Observations from 21 days operation of a plant for the oxidation
#' of ammonia as a stage in the production of nitric acid.
#'
#' Format: 21 cases and 4 continuous variables.
#' Description: The columns are:
#' 1. air flow
#' 2. cooling water inlet temperature (C)
#' 3. acid concentration (%)
#' 4. Stack loss, defined as the percentage of ingoing ammonia
#' that escapes unabsorbed (response)
