This is an R package for emprical likelihood inference under semiparametric density ratio models for multiple samples, including quantile estimation, density estimation, composite hypothesis testing for changes in distributoin functions, etc.
Two memory-efficient algorithms for large-scale L1-type optimization based on subgradient method; C programs with R interface. NOTE: This package is still in alpha (development) stage and is not well documented. Use with caution!
This is the comupter code companying our paper "Statistical modeling and forecasting of fruit crop phenology under climate change" (Environmetrics, 2014). If you really like to try out our method for modeling and predicting phenological events or similar time-to-event data, contact me for the software.
