BS_local_factor {GCCfactor}

Get a bootstrap confidence interval for the local factors

Description

This function employs a bootstrap procedure to obtain confidence intervals for the local factors in block i at time t. See Lin and Shin (2023) for details.

Usage

BS_local_factor(object, i, t, BB = 599, alpha = 0.05)

Arguments

object

An S3 object of class 'multi_result' created by multilevel().

i

An integer indicating the i-th block.

t

An integer specifying the time point at which the CI is constructed.

BB

An integer indicating the number of bootstrap repetition. 599 by default.

alpha

The significance level, a single numeric between 0 and 1. 0.05 by default.

Value

A matrix containing the upper and lower band.
