Data on heart disease

Description

Data containing information on 154 patients, of which only 6 did not have missing values for the characteristics of interest to us. Due to the fact that there are a large number of observations with gaps, we cannot exclude them from consideration. All patients underwent heart surgery; they were divided into g = 2 groups according to gender — female (41 patients) and male (113 patients). For each patient data, the data is measured at t = 4 time points.
