Question 2) Determine which of the FOLLOWING variables are associated with survival status (Death: 0=Alive, 1=Dead). a) b) Initially determine if DBP, SBP, cholesterol and weight, cross- sectionally (i.e. Separately at 1950 and at 1962) ALONG WITH other risk factors /independent variables mentioned below, influenced survival status. NOTE: RUN TWO separate MODELS. Secondly, calculate the change (BETWEEN 1950-1960) in the variables described in a) above and determine ALONG WITH ABOVE RISK VARIABLES their influence on survival status.
