Web applications and teaching tools
I have created web applications to aid epidemiologists in performing calculations and teaching epidemiologic concepts.
Sample size calculator for panel studies
- Calculate the minimal sample size when you have panel data and a continuous outcome
- Accompanies the paper Sample Size Estimation for Random-effects Models: Balancing Precision and Feasibility in Panel Studies in Epidemiology by Scott Weichenthal et al.
- Github repo
E-value calculator
- Calculate the e-value for relative measures, as introduced by Vanderweele and Ding
- Github repo
The misleading odds ratio
- This spreadsheet demonstrates how the average risk difference is the only incident measure of association to correctly estimate a measure of average causal effect (under no assumptions).
- Facilitates the classic epidemiology reading Interpretation and choice of effect measures in epidemiologic analyses by Sander Greenland (1987).
