# clubSandwich

`clubSandwich` provides several cluster-robust variance estimators 

(i.e., sandwich estimators) for ordinary and weighted least squares linear regression models, two-stage least squares regression models, and generalized linear models. 

Several adjustments are incorporated to improve small-sample performance. 

The package includes functions for estimating the variance-covariance matrix and 

for testing single- and multiple-contrast hypotheses based on Wald test statistics. 

Tests of single regression coefficients use Satterthwaite or saddlepoint corrections.

Tests of multiple-contrast hypotheses use an approximation to Hotelling's T-squared distribution. 

Methods are provided for a variety of fitted models, including:

- `lm()`

- `mlm()`

- `glm()` 

- `geeglm()` (from package `geepack`)

- `ivreg()` (from package `ivreg`, when estimated using `method = "OLS"`)

- `ivreg()` (from package `AER`)

- `plm()` (from package `plm`), 

- `gls()` and `lme()` (from package `nlme`)

- `lmer()` (from package `lme4`)

- `robu()` (from package `robumeta`)

- `rma.uni()` and `rma.mv()` (from package `metafor`)
