R/a3_bootstrap.R
boot_ttest.Rd
This function calculates R bootstrapped t-test statistics between x and y. It also calculates a variety of statistics such as percentile confidence intervals, bias, standard error and jackknife-after-bootstrap estimates.
boot_ttest(x, y, alpha = 0.05, R = 1000)
x | a numeric vector |
---|---|
y | a numeric vector |
alpha | significance level. used to calculate confidence intervals |
R | number of replications |
inputs: list containing user inputs
boot: list containing results of bootstrapping, indices used for the pooled sample of x and y, t-statistics for every sample drawn, bias, standard error, jackknife-after-bootstrap
CI: returned if R >= 200. Lower and upper percentile confidence intervals.
