estimatr 1.0.6

CRAN release: 2025-02-28

  • Allows for prediction with lm_lin() when treatment is a factor and/or multi-valued.
  • Adds saved treatment_levels to the returned lm_lin model object.
  • Stops prediction for lm_lin if the treatment values in new data are not a subset of treatment_levels.
  • Standardizes model fit for lm_lin() models with no intercept.
  • Adds tests to ensure identical predictions from lm_lin() models where treatment is either numeric or factorial, and fit with/without an intercept.
  • Adds relevant examples to predict and lm_robust and lm_lin documentation.
  • Adds Molly Offer-Westort as a contributor.
  • Remove functionality for using lh_robust with multiple hypotheses.
  • Restricted functionality for using lh_robust with clustered standard errors to CR0 standard errors.
