Troubleshooting
Problem
How can I use SPSS to calculate the area under the curve for each case in the data file? I have measurements of drug levels in the blood for each case at 9 time points. These time points are unevenly spaced but identical for all cases. Suppose that I plotted drug level as a function of time for each case. I would like SPSS to calculate the area under this curve, using trapezoidal integration, and store it in a new variable. I would also like to calculate and store the maximum drug level for each case and the time point at which that maximum level first appeared for that case.
