Although the BP test was originally developed to deal with both individual and time effects, the version of the BP test to detect only the individual effects seems to have received the most attention. Such a version of the BP test

WebJul 26, 2012 · Breusch Pagan Test for Heteroscedasticity. Breusch Pagan test (named after Trevor Breusch and Adrian Pagan) is used to check for the presence of heteroscedasticity in a linear regression model. Assume our regression model is Y i = β 1 + β 2 X 2 i + μ i i.e we have simple linear regression model, and E ( μ i 2) = σ i 2, where σ i … WebMar 25, 2016 · I watched this video on how to check for heteroskedasticity using Stata, … WebApr 29, 2024 · Results of the test for homoskedasticity (E1): (a) Plot of squared residuals against the predicted Dmeas (Note: data was homoskedastic by Breusch-Pagan test, p > 0.05); (b) Plot of squared residuals against the predicted Lmeas (Note: data was homoskedastic by Breusch-Pagan test, p > 0.05). creative bread basket ideas
