A Deep Probabilistic Model for Customer Lifetime Value Prediction

google/lifetime-value 16 Dec 2019

In this article, we model the distribution of LTV given associated features as a mixture of zero point mass and lognormal distribution, which we refer to as the zero-inflated lognormal (ZILN) distribution.

Computing Extremely Accurate Quantiles Using t-Digests

tdunning/t-digest 11 Feb 2019

We present on-line algorithms for computing approximations of rank-based statistics that give high accuracy, particularly near the tails of a distribution, with very small sketches.

nflWAR: A Reproducible Method for Offensive Player Evaluation in Football

mrcaseb/nflfastr 3 Feb 2018

We discuss how our reproducible WAR framework, built entirely on publicly available data, can be easily extended to estimate WAR for players at any position, provided that researchers have access to data specifying which players are on the field during each play.

Basis-Function Models in Spatial Statistics

msainsburydale/ARSIA_BasisFunctionModels_code 8 Feb 2022

Spatial statistics is concerned with the analysis of data that have spatial locations associated with them, and those locations are used to model statistical dependence between the data.
