     This dataset gives the longitudinal observations of prothrombin
     index, a measure of liver function, for patients from a controlled
     trial into prednisone treatment of liver cirrhosis. Also included
     is the necessary longitudinal  design matrix for the model as
     analysed in Henderson, Diggle and Dobson (2002). This dataset is
     to be used in conjunction with 'liversurv'.

_F_o_r_m_a_t:

     A data frame with longitudinal observations and design matrix for
     75 subjects. The column form is subject id, prothrombin index
     measurement, time, longitudinal design matrix.
