Here’s a more complete version of the R Markdown file: # Permutation Tests for One-Way ANOVA ## Introduction One-way ANOVA is a statistical test used to compare means among three or more groups. However, it can be sensitive to outliers and may not work well when there are only two groups. Permutation tests offer an alternative way of doing one-way ANOVA without assuming normality or equal variances of the data. Here we demonstrate how to use permutation tests in R for one-way ANOVA using a simple linear model A (`y ~ g`) and its extension, model B (`y ~ 1`), where `1` is a constant term.
