Abstract: This command provides a summary table that lists each variable in the master data set and indicates how many variables were affected by the merge update and replace options. This summary table only reflects observations that are in the master data set (_merge==1, 3, 4, and 5). This command sends the merge specification and options to the Stata merge command without modification, without comment, and without any assessment as to whether using the verbose merge makes sense. This command temporarily duplicates all variables in the master data set, thus requiring additional memory equal to the size of the master data set. An option is available that eliminates the need to use this additional memory, but uses more disk space, takes longer, and results in more cryptic output.
