a) State the Gauss Markov assumptions regarding (i) homoschedasticity, (ii) non autocorrelated error terms. b) Test for heteroschedasticity using White test. State the null hypothesis, test statistic and its interpretation. c) Test for autocorrelated errors using Durbin_Watson Statistic test. State the null hypothesis, test statistic and its interpretation. d) Test for autocorrelated errors using Breusch-Godfrey test. State the null hypothesis, test statistic and its interpretation.
