--- title: "Sensitivity, specification curves, and decision stability" output: rmarkdown::html_vignette vignette: > %\VignetteIndexEntry{Sensitivity, specification curves, and decision stability} %\VignetteEngine{knitr::rmarkdown} %\VignetteEncoding{UTF-8} --- ```{r setup, include=FALSE} knitr::opts_chunk$set(collapse = TRUE, comment = "#>") ``` Reasonable preprocessing and modeling choices can change numerical results. eyeprocess therefore represents a defensible specification set explicitly and evaluates each branch under the same extraction contract. ```{r, eval=FALSE} grid <- process_sensitivity_grid(fixation_min_ms=c(60,80,100), pupil_interpolation=c("none","linear","spline"), max_invalid_trial=c(.2,.3,.4)) x <- run_process_sensitivity(data, grid, analysis_fun, extract_fun) summarise_process_sensitivity(x, p_value="p_value") decision_stability(x, p_value="p_value") sensitivity_decision_leverage(x) plot(x, lower="lower", upper="upper") ``` A stable declared multiverse does not validate specifications that were never included. Stability thresholds are reporting conventions, not universal validity cutoffs.
