Stata 15 help for _ms_findomitted

Title

[P] _ms_findomitted -- Find and flag omitted matrix elements

Syntax

_ms_findomitted bmat vmat [, nocheck]

Description

_ms_findomitted searches for zero-valued elements of row vector bmat that correspond to zero-valued diagonal elements of vmat. It then flags those zero-valued elements of bmat as "(omitted)" using the o. operator on the corresponding column stripe element of bmat. The row and column stripes of vmat are also updated if the nocheck option is not specified.

Option

nocheck prevents _ms_findomitted from doing anything with the column and row stripes of vmat. By default, the matrix stripe information in the columns of bmat must agree with the matrix stripe information in the rows and columns of vmat.
