Statistics and probability

Which of the following is correct? (There may be one or multiple correct answers within the list below) Suppose that you are interested in estimating the ceteris paribus relationship between y and x1. You have collected data and run the following sample regression function, and obtained estimates of OLS coefficients. Vi = Bo + Bixa + B2x12 Later on, you have realized that the true population function is: Vi = Bo + Bixa+ u Thus, you run the following sample regression function. Di = Bo + Bixn None of the other statements given in this list can be said without further information The coefficient estimate of x1 in multiple regression analysis can be smaller than the coefficient estimate of x1 in simple regression analysis. The coefficient estimate of x1 in multiple regression analysis will be equal to the coefficient estimate of x1 in simple regression analysis. The coefficient estimate of x1 in multiple regression analysis can be greater than the coefficient estimate of x1 in simple regression analysis.Regression analysis probability question Suppose When doing regression analysis you obtain the regression equation y=10.0x+13 and an r squared value of 0.64. What is the correlation of your data set? A. 0.3 or -0.8 B. 0.8 only C. 0.64 D. 13 Write a code in MATLAB that uses Euler's method to solve the following equation, +i mg kvz = m, with the initial conditions that, to = 0, yo = 0 (consider \"y\" increases downwards) and vo = O (the paratrooper parts from rest). The program must generate graphs of a vs. t; vvs. t, and y vs. t, indicating the variables on the axes and their units \f
