Nonparametric serial interval estimation with uniform mixtures.

PLoS Computational Biology
The serial interval of an infectious disease is a key instrument to understand transmission dynamics. Estimation of the serial interval distribution from illness onset data extracted from transmission pairs is challenging due to the presence of censoring

pyrichlet: A Python Package for Density Estimation and Clustering Using Gaussian Mixture Models

Journal of Statistical Software
Bayesian nonparametric models have proven to be successful tools for clustering and density estimation. While there exists a nourished ecosystem of implementations in R, for Python there are only a few. Here we develop a Python package called pyrichlet,

Nonparametric estimation and specification testing of a two-factor interest rate model [PDF]

We propose a simple, flexible approach to nonparametric estimation and specification testing for a two-factor interest rate model. These methods are illustrated with a Monte Carlo experiment and an empirical example.Nonparametric local linear estimation,

A consistent nonparametric estimation of spatial autocovariances [PDF]

We examine some aspects of estimating sample autocovariances for spatial processes. Especially, we note that for such processes, it is not possible to approximate the expectation by the sample mean, like in the case of time series data.
