Difference between two consecutive rows in SAS
Dataset is shown on right side. Here Visit, Time and Page are given and we need to calculate the duration by subtracting two consecutive rows.
E.g
Duration of Page "A" in Visit 1 is 23:39:23 - 23:34:10.
For Calculating Time difference we first need to convert this into time variable.
data libname.dataset;
set libname.dataset;
time1 = hms (scan(time,1,':'), scan(time,2,':'), scan(time,3,':');
run;
Now this time can be use for calculation. Now, Try the macro below for calculation of duration. For Difference calculation I am using proc sql .
Note: Duration of last page of every visit is marked as Zero (as it can't be calculated).
Copy the macro below in file and for using type
%include "<filename complete path>";
%time_calc( libname,input_dataset,output_dataset,visit,time1,Duration);
