st: right-skewed proportion data

[Jörg Eulenberger <j.eulenberger@web.de>]

Dear Statalisters,

i have a problem with right-skewed dependvariable. The range of
this variable are 0-1 (proportion data 0%-100%). The Distribution looks like poisson, but the values are not discret.

I created the dependvariable by counting the missings (item-non-responce) row wise. Then i
standardize this variable by the number of  all possible variables
(automatic filtering causes different count of vars).

*************
ds
local varnumber `: word count `r(varlist)''
gen varnumber_without_filter_missing = `varnumber'-filter_missing
gen item_non_response_percent = (100/varnumber_without_filter_missing)*number_item_non_response
gen item_non_response_percent_r = item_non_response_percent /100    /* range 0-1 */
******************

I found the article http://www.stata-journal.com/sjpdf.html?articlenum=st0147for handling
proportion data. But what is the right way to handling a right-skewed
(proportion) dependvar? 


Any suggestions?
Thanks,
Jörg
