Dear Statalist
I am confused about some options for the ssc packages `xtivreg2` and `ivreg2`...The helpfile for `xtivreg2` mentions the `cueinit()` and `cueoptions()` options in the syntax description. However, they are not described anywhere else in the helpfile. The helpfile for `ivreg2` mentions neither options (but mentions the `b0()` option). In the 2007 Baum/Schaffer/Stillman paper on ivreg2 in the Stata J, the `cueinit()` and `cueoptions()` options are mentioned in section 4.1, p 479. However, none of the options seem to work for me. For example
Is this a mistake in the documentation, or is something else going on? When searching in the code for `ivreg2` and `xtivreg2`, there are no mentions of the options either, so it seems that they simply don't exist anymore.
I'm using Stata version 12.1. My version of xtivreg2 is 1.0.17 19Feb2015. My version of ivreg2 is 4.1.10 9Feb2016. I've retried removing and reinstalling both packages.
