Quantile Method for Calculation of Resampling Confidence Intervals

Calculate bootstrap confidence intervals for intercept, slope or bias given the vector of bootstrap point estimates.

mc.calc.quantile(Xboot, alpha)

Arguments

Xboot

vector of point estimates for bootstrap samples. The i-th element contains point estimate of the i-th bootstrap sample.

alpha

numeric value specifying the 100(1-alpha)% confidence level for the confidence interval (Default is 0.05).

Value

a list with elements

est

median of bootstrap point estimates Xboot.

CI

confidence interval for point estimate 'est', calculated as quantiles.
