Description Usage Arguments Details Value See Also

Extracts propensity score weights from a ps or mnps object.

1	get.weights(ps1, stop.method = NULL, estimand = NULL, withSampW = TRUE)

`ps1`	A `ps` or `mnps` object.
`stop.method`	Indicates which set of weights to retrieve from the `ps` object.
`estimand`	Indicates whether the weights are for the average treatment effect on the treated (ATT) or the average treatment effect on the population (ATE). By default, `get.weights` will use the estimand used to fit the `ps` object.
`withSampW`	Whether to return weights with sample weights multiplied in, if they were provided in the original `ps` or `mnps` call. Default: `TRUE`.

Weights for ATT are 1 for the treatment cases and p/(1-p) for the control cases. Weights for ATE are 1/p for the treatment cases and 1/(1-p) for the control cases.

Returns a vector of weights.
