Return integer values #1

Closed cstepper closed 5 years ago

cstepper commented 5 years ago

Hi,

just out of curiosity:

Would it be possible to return integer values after running the IPFP while keeping the marginal sum restrictions?

In our usecase, we need to round modelled population figures, and in our result we want to have "number of persons".

Cheers, Christoph

Hi,

Yes, no worries. You simply need to round the elements in $hat.

For instance if the result of Ipfp is stored in res, then simply use round(res$hat).

There are better ways to round the outputs from the Ipfp procedure, see for instance this paper: https://www.sciencedirect.com/science/article/pii/S0198971513000240?via%3Dihub

Cheers,

Johan

Hi Johan,

thanks for your answer, we'll have a look at that paper.

Best, Christoph
