Pesaran's test for cross-correlation among panel units.

Share:

Description

This function implements the procedure for testing for the presence of cross-correlation among panel units using the test proposed in Pesaran (2004).

Usage

1
  Pesaran(resids)

Arguments

resids

a T \times N matrix of residuals from N single-equation models over N time series of length T.

Details

This function should be applied to residuals from individual tests regressions.

Value

The function returns a list of class "htest" containing:

statistic

the test statistic.

parameter

the number N of time series and their length T.

p.value

the p-value of the test.

null.value

the specified hypothesized value under the null.

alternative

a character string describing the alternative hypothesis.

method

a character string indicating the type of test.

data.name

a character string giving the name of the vector of residuals.
