Description: Provides several methods for computing the Quantile Treatment
    Effect (QTE) and Quantile Treatment Effect on the Treated (QTT). The main
    cases covered are (i) treatment is randomly assigned, (ii) treatment is as
    good as randomly assigned after conditioning on covariates (selection on
    observables) using the methods of Firpo (2007)
    <doi:10.1111/j.1468-0262.2007.00738.x>, and (iii) identification is based
    on a Difference in Differences assumption, with support for several
    varieties including Athey and Imbens (2006)
    <doi:10.1111/j.1468-0262.2006.00668.x>, Callaway and Li (2019)
    <doi:10.3982/QE935>, and Callaway, Li, and Oka (2018)
    <doi:10.1016/j.jeconom.2018.06.008>. Version 2.0 adds a unified staggered
    treatment adoption API (built on 'ptetools') for all DiD-based estimators,
    as well as a new lagged-outcome unconfoundedness estimator ('lou_qtt').
