nwcompressobs

Drop observations that no network needs

Syntax 

nwcompressobs

Description

Comresses the observations in Stata. Deletes all unnecessary cases that are not needed to represent the largest network. When the dataset also contains an attribute variable with non-missing data, these cases are not deleted.

Examples 

. nwclear
. nwrandom 20, prob(.2)
. set obs 50
. nwcompressobs

Supported network types

Not applicable - trims trailing empty (all-missing) Stata observations from the dataset; does not read or depend on any network’s own content, directed/valued/two-mode status, or tie values.
