Changes in version 0.1.0.9000 Changes in version 0.1.0 (2026-06-10) Changes in version 0.0.0.9000 - Added the initial development version with HC covariance estimators, normal Wald inference, S3 output, and the PublicSchools dataset. - plot() now supports vcov_hc() objects, producing leverage-versus-adjustment-factor graphics for inspecting the relationship between h_t and g_t. - summary() now prints formal test results, confidence interval checks, and optional emoji markers to improve interpretation of robust inference output. - summary() now keeps displayed test_result decisions consistent with numeric p-values when p-values are displayed as <0.001. - Added tests() as a formal extractor for coefficient-level Wald test results. The function mirrors the API of confint(): an optional parm argument selects coefficients by name or position, and an optional alpha argument recomputes the reject column without affecting the stored p-values or test statistics.
