Many-Armed Bandits in UX Experiments: Faster Testing with Smarter Traffic Distribution
Traditional A/B testing splits incoming traffic equally (50/50%) between design versions A and B. Then, half of the incoming traffic will receive the original version and the other half will receive the new design variation during the experimentation period. This fixed, equal distribution of traffic generates statistically more accurate results with unbiased data, but it […]
An advanced guide to Nuxt testing and mocking
Testing a Nuxt application is not the same as testing plain Vue components. Vue is a frontend framework for building reactive UI components; Nuxt is a full-stack framework built on top of Vue that adds server-side rendering, file-based routing, auto-imports, layouts, middleware, Nitro server routes, and deployment conventions. That extra framework layer is exactly why […]
Testing Interactions in Nonlinear Regression
If the observations were independent (i.e., without blocks or repeated measurements), this model could be fitted using conventional nonlinear regression. My preference goes to drm() function in the ‘drc’ package (Ritz et al., 2015). The coding is reported below: “Performance” is a function of (\(\sim\)) DAS, using a three-parameter logistic function (“fct = L.3()”). Different […]
