get_covar_vif: Get Variance Inflation Factors for a set of covariates

In njhenry/covidemr: Tools for Mapping COVID Excess Mortality

Description

Get Variance Inflation Factors (VIFs), indicating multicollinearity associated with each covariate in a dataset. A VIF value over ~5 indicates high collinearity and might warrant exclusion from a dataset

Usage

get_covar_vif(in_data, covar_names)

Arguments

in_data	Input dataset, in data.table format
covar_names	[char] vector of covariate names, each of which should appear as columns in the dataset

Value

data.table with two fields: 'covar_name' (representing the covariate name) and 'vif' (giving the variance inflation factor for each covariate).
