epinowcast vs KLINK
A side-by-side editorial comparison of epinowcast and KLINK — release velocity, themes, recent moves, and the top alternatives to consider.
epinowcast vs KLINK: at a glance
What is epinowcast?
epinowcast added Gaussian processes to its formula interface and made the sampler twice as fast
epinowcast is a Bayesian nowcasting toolkit for right-truncated epidemiological count data, built on Stan with a brms-style formula interface. Over 2025-2026 it moved from experimental to stable, prepared for CRAN, and broadened past nowcasting proper — 0.6.0's max_delay = 1 support allows purely retrospective fitting of fully reported counts. 0.7.0 in July 2026 is the largest modelling release in the window.
What is KLINK?
Forensic kinship testing with linked STR markers, now peer-reviewed and taking data from anywhere.
KLINK is a Shiny application and R package for kinship testing that accounts for linkage between STR markers, rather than treating all markers as independent. The built-in genetic map covers 50 common STR markers, pairs them dynamically after data loads, and lets the user set the maximum distance at which a pair counts as linked. Custom marker maps can now arrive as Excel files including KLINK's own download files, and a paper describing the tool was published in FSI:Genetics in 2026.

◆ Current state
epinowcast is a Bayesian nowcasting toolkit for right-truncated epidemiological count data, built on Stan with a brms-style formula interface. Over 2025-2026 it moved from experimental to stable, prepared for CRAN, and broadened past nowcasting proper — 0.6.0's max_delay = 1 support allows purely retrospective fitting of fully reported counts. 0.7.0 in July 2026 is the largest modelling release in the window.
◆ Where it's heading
The package is converging on a general formula-driven latent process toolkit rather than a single nowcasting model. rw() and arima() were joined in 0.7.0 by gp(), a Hilbert-space reduced-rank Gaussian process placeable on any module's linear predictor with selectable kernels and an integration order matching arima()'s d. Alongside it, the fixed-effects design and integrated residuals are now centred against the module intercept, which the notes report roughly doubles sampling speed on a weekly random-walk growth model.
◆ Prediction
With CRAN preparation done in 0.6.0 and the model surface substantially widened in 0.7.0, the next release is likely a CRAN submission plus consolidation of the gp() kernels. The release notes repeatedly benchmark against EpiNow2's behaviour, suggesting continued convergence between the two codebases.
KLINK
2.5ANALYTICS
Forensic kinship testing with linked STR markers, now peer-reviewed and taking data from anywhere.
◆ Current state
KLINK is a Shiny application and R package for kinship testing that accounts for linkage between STR markers, rather than treating all markers as independent. The built-in genetic map covers 50 common STR markers, pairs them dynamically after data loads, and lets the user set the maximum distance at which a pair counts as linked. Custom marker maps can now arrive as Excel files including KLINK's own download files, and a paper describing the tool was published in FSI:Genetics in 2026.
◆ Where it's heading
The direction is from fixed panel toward general instrument. Hard-coded linkage pairs gave way to dynamic pairing, the built-in map grew from 18 to 50 markers, the map itself was then moved out to the norSTR package, and the app now accepts custom maps in several file formats and decimal conventions. Method capability tracks the upstream pedsuite rather than KLINK itself: special lumping in pedprobr and pedmut is what allowed complex mutation models in common pedigrees, and the newest release pins pedtools 2.11.0 and pedprobr 1.1.0 for faster likelihoods and better handling of looped pedigrees. Much of the remaining work is unglamorous casework ergonomics, replacing stray Norwegian text in Excel output, controlling table heights, fixing karyogram colours.
◆ Prediction
With the map externalised and custom maps loading from multiple formats, the likeliest next step is broader marker-panel coverage through norSTR rather than changes in KLINK itself. Method gains should continue to arrive as pedprobr and pedmut version bumps.
