- the regression line always passes through mcqwhen the regression line passes through the origin thenA regression line describes the relationship between the dependent and independent variables and can be used to estimate specific points for x or y, provided an individual is supplied with the values of all the other variables but one. True or false
- It is required to use the data given in the table to estimate the parameters of the multiple linear regression equation by any of the estimation methods:It is required to use the data given in the table to estimate the parameters of the simple linear regression equation by any of the estimation methods:Plot the linear regression line y = 3 + 0.5x without using excel with proper labelling
- Suppose the regression in Equation is estimated using LoSTR andLoEL in place of HiSTR and HiEL, where LoSTR = 1 - HiSTR is anindicator for a low-class-size district and LoEL = 1 - HiEL is an indicatorfor a district with a low percentage of English learners. What are thevalues of the estimated regression coefficients?Write down the regression model with the unknown coefficients.If I add the additional condition which is the labor is female using the following: #People who is femalefemale = x*0.46 Will it become dependent variable and how will I do linear regression model by adding this condition?
- Here, mean of X is 3 and the mean of Y is 7. The regression line that predicts Y from X necessarily goes through the point (3,7). True FalseThe predictions made using multiple regression are often more ______ than the predictions made using linear regression with one predictor variable.If the correlation of the X's is equal to 1 or -1, then the regression cannot process. Why?
