mc.calc.bca: Bias Corrected and Accelerated Resampling Confidence Interval

Description

Calculate resampling BCa confidence intervals for intercept, slope or bias given a vector of bootstrap and jackknife point estimates.

Usage

mc.calc.bca(Xboot, Xjack, xhat, alpha)

Arguments

Xboot

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

Xjack

vector of point estimates for jackknife samples. The i-th element contains point estimate of the dataset without i-th observation.

xhat

point estimate for the complete data set (scalar).

alpha

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

Value

a list with elements

est

point estimate for the complete data set (xhat).

CI

confidence interval for point estimate.
