Description: Pre-testing and diagnostic tools for panel data analysis.
        Researchers should run these tests before any panel regression
        to verify modelling assumptions. The package implements: (1)
        the Hsiao (2014, <ISBN:978-1-107-65763-2>) homogeneity F-tests
        (F1/F2/F3), Swamy (1970) <doi:10.2307/1913012> parameter
        heterogeneity test, and Pesaran (2004)
        <doi:10.2139/ssrn.572504> cross-sectional dependence test via
        xtpretest(); (2) missing-data detection, mechanism testing, and
        imputation for unbalanced panels via xtmispanel(); (3)
        quantile-regression cross-sectional dependence tests (T_tau and
        T-tilde_tau statistics) of Demetrescu, Hosseinkouchack and
        Rodrigues (2023) via xtcsdq(); and (4) the panel
        quantile-regression slope homogeneity S-hat and D-hat
        statistics of Galvao, Juhl, Montes-Rojas and Olmo (2017)
        <doi:10.1093/jjfinec/nbx016> via xtqsh(). Together these tests
        address three fundamental pre-testing questions: (i) are slopes
        homogeneous? (ii) is there cross-sectional dependence? and
        (iii) is the panel balanced and is missingness ignorable?
