nwvalidvars

Validate Stata variables for network

Syntax

nwvalidvars 
nodes ,
stub(string)

Description

Validates names of Stata variables that can be used to represent a network of size nodes. Stata variables are generated by combining stub() with a consecutive number. If these Stata variables already exists, the command comes up with a new suggestion for naming variables. This command is mostly used for progamming.

Examples

. nwclear
. nwwebuse gang
. nwvalidvars 10, stub(g)
. return list

Supported network types

Not applicable - a pure Stata-variable-name bookkeeping utility (finds a collision-free stubN variable-name pattern for a given node count); does not read or depend on any network’s own content, directed/valued/two-mode status, or tie values at all.

Stored results

• r(stub) stub used to generate Stata variable names
• r(valid) “true” when Stata variables do not already exist, “false” otherwise
• r(validvars) list of valid Stata variables
