A method about Considering Heteroskedastic panel data in economical Analyses are *** suppose test of model and consistent estimator of coefficient are *** parameter estimation are resolved when μ i∶(0,w 2 i),v it ∶i.i.d(0,σ 2 i) in model (1).At last,We give an empirical analysis for Heteroskedastic problems.
