Flexible Low-Rank Statistical Modeling with Side Information
William Fithian, Rahul Mazumder
We propose a general framework for reduced-rank modeling of matrix-valued data. By applying a generalized nuclear norm penalty we can directly model low-dimensional latent variable…

Semiparametric Exponential Families for Heavy-Tailed Data
William Fithian, Stefan Wager
We propose a semiparametric method for fitting the tail of a heavy-tailed population given a relatively small sample from that population and a larger sample from a related backgro…

Local case-control sampling: Efficient subsampling in imbalanced data sets
William Fithian, Trevor Hastie
For classification problems with significant class imbalance, subsampling can reduce computational costs at the price of inflated variance in estimating model parameters. We propos…
