#' Gasoline Yield Data from Prater (1956)
#'
#' A dataset containing 32 observations on gasoline yield under different experimental conditions.
#' The response variable \code{yield} is a proportion (0 < yield < 1), making it suitable for beta regression.
#'
#' @format A data frame with 32 rows and 6 variables:

#'   \item{yield}{numeric: proportion of crude oil converted to gasoline}
#'   \item{batch}{factor: 10 unique batches of crude oil}
#'   \item{temp}{numeric: temperature (Fahrenheit)}
#'   \item{gravity}{numeric: crude oil gravity}
#'   \item{pressure}{numeric: pressure}
#'   \item{temp10}{numeric: temperature (scaled)}
