Due: Jan 22 ECN 702 Econometrics II 1. Given data on (x) for i,n, consider the following least square problem for a simple linear regression. bobi We assume the four linear regression model assumptions dicussed in class hold. 6) Compute the partial derivatives of the objective function. (ii) Put the derived partial derivatives in (i) equal to zeros. Explain why the resulting equa- tions are called ‘normal equation. (Hint: two n-dimesional vectors (voi-i and (wi)-1 are normal(-orthogonal) if Σ(-1 uiv.-0.)...

QUESTION 1 Consider the following OLS regression line (or sample regression function): wage =-2.10+ 0.50 educ (1), where wage is hourly wage, measured in dollars, and educ years of formal education. According to (1), a person with no education has a predicted hourly wage of [wagehat] dollars. (NOTE: Write your answer in number format, with 2 decimal places of precision level; do not write your answer as a fraction. Add a leading minus sign symbol, a leading zero and trailing...

1. Draw a graph of the equation: y 4.9 m/s2 t2 with horizontal axis (t) spanning from O to 2 seconds and vertical axis (v) spanning from 0 to 5 meters. (Note: This is different from last week's pre-lab ir which you graphed y vs. t2, here we are asking for you to graph y vs. t). 2. In generating a best fit...
We have the following hypothetical data for the independent variable x
Simple Linear Regression (SLR) We have the following hypothetical data for the independent variable x (other names: regressor, covariate, or explanatory variable) and the dependent variable y (regressand). (a) Use Excel to draw a y-x scatter diagram with y on the vertical axis. Add the linear trend line. (b) Complete the table. Use 5 decimals throughout your calculations if applicable. (c) Give an equation for and manually calculate the slope b1. The table aids your calculations. (d) Give an equation for and calculate...
