Implement WEC for BIFIEsurvey #5

Open beckerbenj opened 1 year ago

beckerbenj commented 1 year ago

Currently, option WEC for cross level differences is only available for engine = "survey". An BIFIEsurvey implementation would mean a substantial increase in performance.

However, it is unclear whether and how contrast coding can be adapted within BIFIEsurvey.

weirichs commented 1 year ago

To my knowledge, adapting WEC in BIFIEsurvey needs C++ implementation which is not possible for us (at least for me) to realize.

Implement multicore instead?

beckerbenj commented 1 year ago

Would it be worthwhile discussing this with Alexander Robitzsch?

weirichs commented 1 year ago

Alex was not so fond of WEC; he said he would rather solve this via bootstrap. In this respect, I don't know how enthusiastic he would be about an implementation.

beckerbenj commented 1 year ago

True, thanks for the reminder!

Would multicore implementation be a promising alternative for performance gains as you suggested? Should I rename the issue/open a new one?

weirichs commented 1 year ago

I think so. However, it might be a little tough to implement. More arguments would be added to the function, which does not improve the clarity.
