WebUnlike the traditional Breusch-Pagan (1980) LM test, the CD test is applicable for a large number of cross-sectional units (n) observed over T time periods. Recently, Sara–dis, Yamagata and Robertson (2009) develop a test for cross-sectional dependence based on Sargan™s di⁄erence test in a linear dynamic panel data model, in which WebJul 2, 2024 · The Breusch-Pagan is preferable to a standard White test from a practical …

This particular heteroskedasticity specification was motivated by the observation that in many financial time series, the magnitude of residuals appeared to be related to the magnitude of recent residuals. ARCH in itself does not invalidate standard LS inference. WebThe test is compatible with any consistent panelmodel for the data at hand, with any specification of effect (except for test = "bcsclm" which requires a within model with either individual or two-ways effect). E.g., specifying effect = "time" or effect = "twoways" allows to test for residual cross-sectional dependence after the introduction of ...

It was independently suggested with some extension by R. Dennis Cook and Sanford Weisberg in 1983 (Cook–Weisberg test). Derived from the Lagrange multiplier test principle, it tests whether the variance of the errors from a regression is dependent on the values of the independent variables.
