Theoretical questions: Regression without intercept(40 pts) In this question, we consider a two-variable regression model when there is no intercept in the model: There is no intercept x0 in the model. Suppose we have n different samples. Then answer the following questions: (a) Write the design matrix X for our model, using the subscript notation we introduce in class.(10 pts)
In class we discussed internal benchmarking of a process, i.e., gauging process performance relative to worst-, practical-worst-, and best-case performance. An alternative is external benchmarking of a process, where process performance is measured via comparison to another system. What are some pros and cons of both internal and external benchmarking of process performance?

3. Consider a random sample Yı, ,Yn from a Uniform[0, θ]. In class we discussed the method of ,y,). We moment estimator θ-2Y and the maximum likelihood estimator θ-maxx,Yo, derived the Bias and MSE for both estimators. With the intent to correct the bias of the mle θ we proposed the following new estimator -Imax where the subscript u stands for "unbiased." (a) Find the MSE of (b) Compare the MSE of θυ to the MSE of θ, the original...
Question 7 Not yet answered Ma ged out of 1.00 As discussed in the class, Companies like Ford, Chevy, IBM use open space environment (cubicles) in the workplaces and the main reason for this Flag question Select one: a. is to save money b. is to improve/facilitate communication between employees c. is to maintain safety regulations Previous page Next page
Theoretical questions: Regression without intercept(40 pts) In this question, we consider a two-variable regression model when there is no intercept in the model: There is no intercept zo in the model. Suppose we have n different samples. Then answer the following questions: (a) Write the design matrix X for our model, using the subscript notation we introduce in class.(10 pts) (b) Write the explicit solution of βί and ß2, in terms of Σ'al ril, Ση! x2, Σ¡al 2ilxi2Σ aily, and...
In class we discussed the <Process Selection Matrix> and the necessity of matching product mix and process pattern. In this product-process matrix, different combinations of process patterns and product mix are displayed. Absent a unique strategy, the importance of being close to the diagonal of the matrix was emphasized, because otherwise a company will pay either an "opportunity costs" (being above the diagonal), or “out-of-pocket cost” (being below the diagonal). Please explain those two concepts with your own language.
3. In class we discussed the heat conduction problem with the boundary conditions a(0, t) 0, t4(1,t)-0, t > 0 and the initial condition u(r,0) f(a) We found the solution to be of the form where (2n-1)n 1,2,3,. TL 20 Now consider the heat conduction problem with the boundary conditions u(0, t) 1,u(T, t)0, t>0 and the initial condition ur,0) 0. Find u(r,t). Hint: First you must find the steady state. 3. In class we discussed the heat conduction problem...
