Does anyone have a SAS Macro for chained equipercentile and frequency estimation equipercentile equating methods?

I would appreciate any help.

Thanks

Thank you Mohamed, I have this article which was slightly useful for the linear equating methods I am studying. Frequency estimation and chained equipercentile equating methods are non-linear and they function differently.

Out of my area, but came across the following article that may be of help: http://analytics.ncsu.edu/sesug/2013/BtB-11.pdf

Thank you Arthur, I have this article and another one presented at SESUG 2013 which were quite useful for Tucker, Levine, linear, and mean methods. I am struggling with the two non linear methods: Frequency estimation and chained equipercentile equating methods.

thanks again and happy new year

If you haven't looked at the following, as well, it also appears to contain some useful info, but all of the code is in R: http://cran.r-project.org/web/packages/equate/vignettes/equatevignette.pdf
