Consider the following simple regression model: where the e, are independent errors with E(ed-0 and var(et)-Ơ2X? a. In this case, would an ordinary least squares regression provide you with the best b. c. linear unbiased estimates? Why or why not? What is the transformed model that would give you constant error variance? Given the following data: y = (4,3,1,0,2) and x = (1,2,1,3,4) Find the generalized least squares estimates of β1 and β2 (Do this by hand! Not with excel)

1. Refer to the Class Commute Data, and let the independent variable Distance (between home and school) and the dependent variable Leave (one-way commute time to school). Using matrix method and the selected variables from the Class Data, obtain the following for an OLS simple linear regression model: Matrices Y, X and ß a. ons developed by the method of least squares c. Get B from (b), and write the fitted regression line. Return Home Leave Home to From Schoo...

In
cell C6, insert a Scatter Chart for the Returns
Completed versus Return Price data from the Data
worksheet. You may be used to seeing Price placed on the Y-axis
from other economics courses, but in this problem we are using
price as the independent variable.

1. Introduction In recent years, nanoclays have been the object of particular interest for many scientists and researchers in chemistry, physics, engineering and biology due to their excellent properties as well as their sustain- ability [1-3]. For instance, they represent the starting point to the de velopment of smart materials for drug delivery (4-9), food packaging [10-12), environmental remediation and wastewater treatment [13], cultural heritage [14–17and...
