IPF with integer results

[Viktoria]

Hi,

I am wondering if ther is a way to obtain integer results with iterative proporional fitting procedure? 

Thank you!

I don't think so. The output from IPF is a fitted (predicted) model, where each cell shows an expected value of the model. These are unlikely to be integers.

Think about the problem of tossing a fair coin. If you toss the coin 7 times, the expected number of heads is 3.5.  You can't make this expected value an integer. A similar example is the expected number of appearances for each face on a six-sided die after 20 rolls. The fitted model does not have integer values.

Thank you very much!
