Error when running rk_rake #91

Open radders opened 4 years ago

radders commented 4 years ago

When running the rk_rake command, I'm getting this error :

Error in if (!sum(weights_dec%%1) > 0) { : missing value where TRUE/FALSE needed

The arguments con, inds, vars look correct.

Any idea what could be causing this? First time I've used the package.

Thank

Are you able to share some of your data so I can replicate the error? Happy to take a look.

Thanks for having a look at this. I can't show the individuals data but the structure is :

person_id, sex, oa_code, age_band, age_sex, oac_grp and it has just over 3,000 rows.

I'm using the code from Roger Beecham's tutorial here : http://homepages.see.leeds.ac.uk/~georjb/predictive-analytics/assignment/01-simulating-behaviour/

The other data attached is from the census.

Hi Rob,

I've just emailed you an answer as well.

I think what was causing the error was that you had a zone that required lots of people of OAC group 3, but only 2 individuals of that group. These also both happened to be male 35-64, so the algorithm had no individuals of other age/sex combinations to simulate.

I've removed these and the simulation works, which I've sent to you. Please leave this issue open as I want to incorporate a way to test for errors of this type to provide feedback to the user. I'll have to come back to this, though.
