- Explain the term "Autoregressions"? Define The First-Order Autoregressive Model?a) Do these data provide good evidence that increasing the stirring rate causes the yield to increase, within the range of the data? Or might the result be due to confounding? Explain.What is a situation where you would test for homogeneity?
- Explain, If the population regression function changes over time, then OLS estimates neglecting this instability are unreliable for statistical inference or forecasting.?What do you mean by Generalized method of moments? illustrate regression model with exogenous variables Z?Find kurtosis by using ungroup data given in the picture using quartile deviation, make sure to arrange data before solving question.
