Description: Provides inverse-free high-dimensional location tests for two-sample
    and general linear hypothesis testing (GLHT) problems under equal or unequal
    covariance structures. The package implements classical normal-approximation
    procedures, scale-invariant procedures, normal-reference procedures based on
    covariance-matched Gaussian companions, and F-type normal-reference
    calibrations for heteroscedastic Behrens-Fisher and GLHT settings. Implemented
    two-sample normal-approximation and scale-invariant procedures include Bai and
    Saranadasa (1996) <https://www.jstor.org/stable/24306018>, Chen and Qin
