densityratio 0.2.4

densityratio 0.2.3

• update loocv procedure in ulsif to work with unconstrained kernel weights
• update lhss to perform unconstrained optimization (aligned with loocv procedure of ulsif)
• small formal check to stop when negative regularization parameters are supplied

densityratio 0.2.2

• update plot_bivariate() to depend on ggh4x to remove empty panels, instead of a grob (such that it remains a ggplot) object
• update link in readme

densityratio 0.2.1

• patch test files to work with the new upcoming ggplot release
• update link readme

densityratio 0.2.0

• First CRAN release of the densityratio package.
• Estimation methods kliep(), kmm(), lhss(), naive(), spectral(), ulsif().
• Cross-validation for all methods incorporated (except naive).
• S3 methods predict(), plot(), print() and summary() incorporated.
• Extensive checks for input data and parameters.
