#' The hip joint data set
#' 
#' The location of the hip joint centre (HJC) is required for 
#' calculations of hip moments, the location and orientation of 
#' the femur, and muscle lengths and lever arms. In clinical 
#' gait analysis, the HJC is normally estimated using linear 
#' regression equations based on normative data obtained from
#' adult populations. There is limited relevant anthropometric 
#' data available for children, despite the fact that clinical 
#' gait analysis is predominantly used for the assessment of 
#' children with cerebral palsy.
#' 
#' The data set has 32 rows and 10 columns. 
#' Each row corresponds to a patient and columns to a variable of
#' interest. The variables are:
#' \describe{
#' \item{Cer}{does the patient have cerebral palsy.}
#' \item{Sex, Age, Mass}{Patient variables}
#' \item{PW}{Pelvic width.}
#' \item{PD}{Pelvic depth.}
#' \item{LL}{Leg length.}
#' \item{x,y,z}{the coordinates of the HJC.}}
