lmw News and Updates

lmw 0.0.2

• Changed the var argument in plot(., type = "extrapolation") to variables (var still works as an abbreviation).

• Added a unit testing framework.

• Weights now have an average of 1 in each treatment group. This only affects the display of the weights, making it easier to assess extreme weights, but does not affect balance or any other property of the weights.

• When using cluster-robust standard errors in lmw_est(), the degrees of freedom for the corresponding t-testing as now computed as one less than the number of clusters to be consistent with other software.

• "IPWRA" is now an acceptable alias for "WLS" when supplied to the dr.method of lmw() with base weights. IPWRA is the name Stata gives to the same estimator.

• When a weightit or matchit object is supplied to obj in lmw() or lmw_iv(), the focal component of the supplied object is automatically supplied and does not need to be specified. A warning will be thrown if focal is supplied and differs from the focal component of the supplied object.

• Errors are prettier.
