Describe Image Patterns in Natural Structures
A computational tool to describe patterns in black and white images from natural structures. 'bwimage' implemented functions for exceptionally broad subject. For instance, 'bwimage' provide examples that range from calculation of canopy openness, description of patterns in vertical vegetation structure, to patterns in bird nest structure.

An interface to the Bayesian Weighted Sums model implemented in 'RStan'.
It estimates the summed effect of multiple, often moderately to highly correlated,
continuous predictors. Its applications can be found in analysis of exposure mixtures.
The model was proposed by Hamra, Maclehose, Croen, Kauffman, and
Newschaffer (2021) <doi:10.3390/ijerph18041373>.
This implementation includes an extension to model binary outcome.

Nonparametric conditional survival function for successive
survival times
This R package implements the conditional survival
function described at 'Nonparametric bivariate estimation for
successive survival times' (C. Serrat and G. Gómez, 2007).
