densratio: New R Package for Density Ratio Estimation

1. Overview Density ratio estimation is described as follows: for given two data samples $x$ and $y$ from unknown distributions $p(x)$ and $q(y)$ respectively, estimate $$ w(x) = frac{p(x)}{q(x)} $$ where $x$ and $y$ are $d$-dimensional real numbers. The estimated density ratio function $w(x)$ can be used in many applications such as the inlier-based outlier detection [1] and covariate shift…
