Visualise and Analyse Bathymetric Survey Data with R

December 13, 2025 | Peter Prevos

The first step in the value chain for water utilities is extracting water from natural sources, such as rivers, groundwater, oceans, or reservoirs. Water managers and the public alike are interested in knowing how much water a reservoir currently holds. This is not an easy problem to solve, as it ...

Functional Analysis of Networks with freeCount

December 12, 2025 | morphoscape

Functional analysis is useful for determining the functions of a set of interesting genes. These gene sets can be lists of genes produced from different analysis, including weighted gene co-expression network analysis (WGCNA). The freeCount FA app will help you perform functional analysis of gene sets, which can be produced ...

Network Analysis with freeCount

December 11, 2025 | morphoscape

Weighted gene co-expression network analysis (WGCNA) is used to investigate the function of genes at the system-level. In a network analysis genes with similar patterns of expression are grouped together into modules. The sets of genes in these modules are co-expressed as a result of shared biological functions, pathways, tissues, ...

Smoothed ROC Curves, Calculus and Curvature

December 11, 2025 | Joseph B. Rickert

A common use of ROC (Receiver Operating Characteristic) curves in data science is to evaluate performance of binary classifiers. In this use case, the data set is usually a sample from a population and so the ROC curve itself is a random object. Although it is not common to have ...

Un-debunking the GAMLSS myth

December 11, 2025 | Achim Zeileis

Generalized additive models for location, scale, and shape (GAMLSS) are popular for estimating reference equations, e.g., for lung function measurements. A recent paper claimed to 'debunk' the GAMLSS myth in this context by showing that much ...

Haskell IS a Great Language for Data Science

December 4, 2025 | Jonathan Carroll

I’ve been learning Haskell for a few years now and I am really liking a lot of the features, not least the strong typing and functional approach. I thought it was lacking some of the things I missed from R until I found the dataHaskell project. There h... [Read more...]
