Percentile bootstrap for the proportion of variance in outcome
explained by group, resampling observations jointly so the group
structure travels with each resample.
Usage
eta_sq_ci(outcome, group, R = 2000, conf.level = 0.95, seed = NULL)
Arguments
- outcome
A numeric vector.
- group
A grouping vector of the same length.
- R
Integer. Number of bootstrap resamples. Defaults to 2000.
- conf.level
Confidence level. Defaults to 0.95.
- seed
Integer or NULL. When supplied, sets the random seed.
Value
A named numeric vector: estimate, lower, upper. The bounds
are NA with fewer than 3 complete observations or fewer than 2 groups.
Examples
eta_sq_ci(mtcars$mpg, mtcars$cyl, seed = 42)
#> estimate lower upper
#> 0.7324601 0.6316254 0.8460837
