Can this design detect the effect it is looking for? Simulation-based power, minimum designs, and detection ceilings for precision psychotherapy studies under therapist nesting.

Local-first construct and operational-definition canvas for research-methods planning.

Multi-omic DL pipeline proposal: emphasizes the clinical + modeling angles

This repository showcases key study designs used in public health research, providing a practical, hands-on learning resource for students and early-career researchers. It covers the full research workflow—from problem definition and study design to statistical analysis and interpretation—using structured examples and synthetic datasets.

The case time series design

This repository is used for a simulated scripted exposure study in Potsdam. The aim of the study is to assess air quality using sonification. The study design should ensure robust air quality values and good comparability during the study.

A tool to estimate the power of detecting a difference in smolt-to-adult ratios (SARs) between transported and migrant salmon

Sample size estimation for single cell studies

Sample-size & power calculator — Python package + Claude Code plugin

Production code for adaptive behavioral choice studies on human cognition in probabilistic situations (aka decisions under risk).

Statistical tool for estimating precision of smolt-to-adult ratio from PIT-tag data

A statistical tool to conduct an a priori analysis of the precision and accuracy of a maximum likelihood estimator of the relative reproductive success (RRS) of hatchery-origin spawners
