IIS Consistency Correction

Description

Consistency correction for estimate of residual variance when using impulse indicator saturation.

Usage

isvarcor(t.pval, sigma)

Arguments

t.pval

numeric value. the p-value of selection in the impulse indicator saturation model.

sigma

numeric value. The estimated standard deviation of the residuals from the impulse indicator saturation model.

Details

The Johansen and Nielsen (2016) impulse-indicator consistency correction for the estimated residual standard deviation.

Value

a data frame containing the corrected standard deviation $sigma.cor and the correction factor used $corxi
