Subject | st: New version of -xsvmat- on SSC |
Date | Tue, 01 Oct 2013 12:06:29 +0100 |
The -xsvmat- package is described as below on my website, and is an extended version of -svmat-. The new version adds an option -from(matrix_expression)-, specifying an alternative source for the input matrix, which can now be an arbitrary Stata matrix expression instead of an existing Stata matrix. For instance, in the Stata -auto- data, the user may type
regress mpg weight length price foreign xsvmat, from(r(table)') rowname(parm) names(col) rowlab(label) list(,)and create and list a dataset similar to those produced by the SSC package -parmest-, but with variable names conforming to a style that seems to be officially approved by StataCorp. These output datasets can alternatively be saved to a disk file and/or written to the memory, overwriting the original dataset, and can then be used to produce plots and/or tables.
I would like to thank Vince Wiggins of StataCorp for some helpful advice, at the 2013 UK Stata User Meeting, on the syntax to be used for this package.

It creates an output dataset (or resultsset), with one observation per row of either an existing matrix or the result of a matrix expression, and data on the values of the column entries in that row, and, optionally, extra variables specified by the user. The output dataset created by xsvmat may be listed to the Stata log, or saved to a disk file, or written to the memory (overwriting any pre-existing dataset).
