Practical 'R' Packaging in 'Docker'
Streamline the creation of 'Docker' images with 'R' packages and dependencies embedded. The 'pracpac' package provides a 'usethis'-like interface to creating Dockerfiles with dependencies managed by 'renv'. The 'pracpac' functionality is described in Nagraj and Turner (2023)
'eXtra' / 'eXperimental' Functionality for Robust Statistics
Robustness -- 'eXperimental', 'eXtraneous', or 'eXtraordinary'
Functionality for Robust Statistics. Hence methods which are not well established,
often related to methods in package 'robustbase'. Amazingly, 'BACON()', originally by

Hidden Markov Models with Discrete Non-Parametric Observation Distributions
Fits hidden Markov models with discrete non-parametric observation distributions to data sets. The observations may be univariate or bivariate. Simulates data from such models. Finds most probable underlying hidden states, the most probable sequences of such states, and the log likelihood of a collection of observations given the parameters of the model. Auxiliary predictors are accommodated in the univariate setting.
Vegetated Filter Strip and Erosion Model
Empirical models for runoff, erosion, and phosphorus loss
across a vegetated filter strip, given slope, soils, climate, and
vegetation (Gall et al., 2018)

Discretised Beta Distribution
Tools for working with a new versatile discrete distribution, the db ("discretised Beta") distribution. This package provides density (probability), distribution, inverse distribution (quantile) and random data generation functions for the db family. It provides functions to effect conveniently maximum likelihood estimation of parameters, and a variety of useful plotting functions. It provides goodness of fit tests and functions to calculate the Fisher information, different estimates of the hessian of the log likelihood and Monte Carlo estimation of the covariance matrix of the maximum likelihood parameter estimates. In addition it provides analogous tools for working with the beta-binomial distribution which has been proposed as a competitor to the db distribution.
Optimal Pricing of Assets with Fixed Expiry Date
Calculates the optimal price of assets (such as airline flight seats, hotel room bookings) whose value becomes zero after a fixed ``expiry date''. Assumes potential customers arrive (possibly in groups) according to a known inhomogeneous Poisson process. Also assumes a known time-varying elasticity of demand (price sensitivity) function. Uses elementary techniques based on ordinary differential equations. Uses the package deSolve to effect the solution of these differential equations.
Utilities for SNP-Based Kinship Analysis
Utilities for single nucleotide polymorphism (SNP) based kinship analysis
testing and evaluation. The 'skater' package contains functions for importing, parsing,
and analyzing pedigree data, performing relationship degree inference, benchmarking
relationship degree classification, and summarizing identity by descent (IBD) segment data.
Package functions and methods are described in Turner et al. (2021) "skater: An R package
for SNP-based Kinship Analysis, Testing, and Evaluation"
Safe Anytime-Valid Inference
Functions to design and apply tests that are anytime valid. The
functions can be used to design hypothesis tests in the prospective/randomised
control trial setting or in the observational/retrospective setting. The
resulting tests remain valid under both optional stopping and optional
continuation. The current version includes safe t-tests and safe tests of
two proportions. For details on the theory of safe tests, see
