- TEST and TESTED are auxiliary binary features indicating whether the patient had a cholesterol test in this quarter (encompassing HDL, LDL, TRI, TCL and TC/HDL), and whether the patient has ever had a cholesterol test respectively. If the patient has any of the listed elements tested in a quarter the value of TEST will be 1, otherwise 0. In a patient’s time-series, the value of TESTED will be 0 prior to the patient having their first cholesterol test. Once the patient has had a cholesterol test, the value of TESTED will switch to 1 and stay at 1 for the remainder of the time-series. The statistics for TEST and TESTED are the number of quarters in the entire data set where the feature contained a 1 and its relative percentage
