PU/DSS/OTR. Testing for random effects: Breusch-Pagan Lagrange multiplier (LM). The LM test helps you decide between a random effects regression and a simple. OLS regression. The null hypothesis in the LM test is that variances across entities is zero. This is, no significant difference across units (i.e. no panel effect).
In statistics, the Breusch–Pagan test, developed in 1979 by Trevor Breusch and Adrian Pagan, is used to test for heteroskedasticity in a linear regression model. It was independently suggested with some extension by R. Dennis Cook and Sanford Weisberg in 1983. It tests whether the variance of the errors from a

I am conducting a regression model in stata to determine the impact of paternity leave on several labour market outcomes. The regression looks like: y = dummy + linear + linear + squared.

In the context of large T and small N, the LM test statistic proposed by Breusch and Pagan (1980) can be used to test for cross-sectional dependence (see help xttest2). However, in most cases, cross-sectional time-series data sets come in the form of small T and large N. In this case the Breusch-Pagan test is not valid.
