2. Consider the simple linear regression model: where e1, .. . , es, are i.i.d. N (0, o2), for i= 1,2,... , n. Suppose that we would like to estimate the mean response at x = x*, that is we want to estimate lyx=* = Bo + B1 x*. The least squares estimator for /uyx* is = bo bi x*, where bo, b1 are the least squares estimators for Bo, Bi. ayx= (a) Show that the least squares estimator for...
I need to plot a histogram for estimates of Beta_0 and Beta_1 (over the 100 simulations). I know I can use the coefficients function with the model to display these estimates for each simulation, but how can I access them individually, or save them to a column vector such that I can plot the histogram as needed? Suppose we want to simulate the following linear model: Bo + BiX; + Ei where ti~ N(0,22). Assume Xi~ N(0,12), Bo = 0.5...
i paid my last dollars for help and you people give me the wrong answer or dont even answer my question!!! im failing my class and no one helps me! im sick and tired! i have to post the same question multiple times just so someone can see it. uncc.instructure.com Partial Question 14 4/16 pts Fifty male subjects drank a measured amount z(in ounces) of a medication and the concentration y (in percent) in their blood of the active ingredient...
