Changelog • RobinCar2

RobinCar2 0.2.1

Now multiple stratification variables are supported in robin_surv by adding them on the right-hand side of the treatment formula.

There will be no more spurious warnings in robin_surv during the hazard ratio estimation coming from the variance calculation: Now the variance is only calculated after the hazard ratio estimate is obtained.
When adjusting for a single factor covariate, or when the covariate is strongly correlated with a strata variable in robin_surv, the function now works correctly and does not fail with a “singular design matrix” error any longer.
Fixed a bug in covariate-adjusted survival function estimation in robin_surv which could occur when there are character covariates with values only appearing in one treatment group, which could have led to incorrect results.

CRAN release: 2025-09-09

Add survival analysis with log-rank test and hazard ratio estimation.
Add log_odds_ratio and log_risk_ratio function for inference.
Add contrast_mat to treatment_effect object.
Add confint to obtain confidence interval for prediction_cf and treatment_effect object.

Previously in robin_glm, vcovG is always used regardless the variance type argument. This is fixed now.
