What is the equation for your model?

We collected teacher ratings for 25 courses taught by an instructor over a sis-year period. The students ratings of the instructor are on a scale of 1 to 9. We found that The linear regression equation is Anerape Rating 7.88-0.068 Numer of Studenta 1interpret the slope of this model including units The average rating decreases * per each additional student 2.

Q12. Suppose we are running gradient descent to fit a logistic regression model with 0 E R*+1. Suggest one way to check whether the learning rate « is set properly and that gradient descent is running correctly.

What do you mean by Generalized method of moments? illustrate regression model with exogenous variables Z?

Due in 3 hours, 41 minutes. Due Sat 04/18/2020 11:59 pm Show Intro/Instructions A regression was run to determine if there is a relationship between hours of study per week (x) and the final exam scores (y). The results of the regression were: у-ах+b a=6.704 b=30.59 p2=0.972196 r=0.986 Use this to predict the final exam score of a student who studies 8.5 hours per week, and please round your answer to a whole number.
