Work in Excel, create a button using macros. The goal is as follows: there is a matrix of 50x3 (50 patients, each has 3 parameters, the first parameter is x, the second parameter is y, the third parameter is z). Find - the minimum and maximum of each parameter, delta of each parameter (max-minimum). Next, find G1=Xmin, G2=G1+delta, G3=G2+delta, G4=G3+delta of each parameter. Build a 3-dimensional space with points G1, G2, G3, G4. Count how many patients were in each interval. If you do it today, I will send you an Excel file with the original data.
