mmbcv 1.0.0

• Added heterogeneity_test() for testing equality of transition-specific effects.
• Added linear_trend_test() for testing GLS linear trends.
• Added order_restricted_test() with chi-bar-square inference.
• Added support for coefficient subsets and user-specified transition scores.
• Created separate help pages for the three tests.
• Reorganized internal testing functions into separate source files.

mmbcv 0.4.0

• Added heterogeneity_test() for an omnibus Wald test of equality among selected transition-specific coefficients.
• Added linear_trend_test() for one- or two-sided generalized least-squares trend tests with equally or unequally spaced transition scores.
• Added order_restricted_test() for monotone increasing or decreasing alternatives using a chi-bar-square reference distribution.
• All three tests accept integer, logical, or character coefficient selection through index and work with any conformable covariance estimator returned by MMBCV().
• The order-restricted test calculates analytic chi-bar-square weights for one or two inequalities and simulation-based weights for higher dimensions. It returns the weights, weight Monte Carlo standard errors, and p-value Monte Carlo standard error, and accepts precomputed weights when desired.
