Estimate variance for each group and bootstrap the alpha-confidence intervals.
Usage
resample_variance(data, alphas = 0.05, M = 1000)
Arguments
- data
Data.frame with the first column the values and the second column
the group names
- alphas
Vector of significances for confidence intervals, defaults to 0.05
- M
Numeric for the number of iterations in the resampling
Value
Matrix with variance and alpha-confidence intervals for each group
Examples
data <- data.frame(
"value" = c(rnorm(14, sd = 2), rnorm(6), rnorm(20, mean = 2)),
"group" = c(rep("A", 14), rep("B", 6), rep("C", 20))
)
