moderndid.wboot_drdid_rc2(y, post, d, x, i_weights, n_bootstrap=1000, trim_level=0.995, random_state=None)[source]#

Compute bootstrap estimates for locally efficient doubly-robust DiD with repeated cross-sections.

Implements the bootstrap inference for the locally efficient doubly-robust difference-in-differences estimator with repeated cross-section data. This version uses outcome regression on both treatment and control groups.

Parameters:
ynumpy.ndarray

A 1D array representing the outcome variable for each unit.

postnumpy.ndarray

A 1D array representing the post-treatment period indicator (1 for post, 0 for pre) for each unit.

dnumpy.ndarray

A 1D array representing the treatment indicator (1 for treated, 0 for control) for each unit.

xnumpy.ndarray

A 2D array of covariates (including intercept if desired) with shape (n_units, n_features).

i_weightsnumpy.ndarray

A 1D array of individual observation weights for each unit.

n_bootstrapint

Number of bootstrap iterations. Default is 1000.

trim_levelfloat

Maximum propensity score value for control units to avoid extreme weights. Default is 0.995.

random_stateint, RandomState instance or None

Controls the random number generation for reproducibility.

Returns:
numpy.ndarray

A 1D array of bootstrap ATT estimates with length n_bootstrap.
