Description: Generates balancing weights for causal effect estimation
        in observational studies with binary, multi-category, or
        continuous point or longitudinal treatments by easing and
        extending the functionality of several R packages and providing
        in-house estimation methods. Available methods include those
        that rely on parametric modeling, optimization, and machine
        learning. Also allows for assessment of weights and checking of
        covariate balance by interfacing directly with the 'cobalt'
        package. Methods for estimating weighted regression models that
        take into account uncertainty in the estimation of the weights
        via M-estimation or bootstrapping are available. See the
        vignette "Installing Supporting Packages" for instructions on
        how to install any optional package 'WeightIt' uses, including
        those that may not be on CRAN.
