In a simple regression model, the slope (b1) represents predicted value of Y when X = 0. change in estimated Y per unit change in X. predicted value of Y. variation around the sample regression line.
2. In a typical simple linear regression model, explore the relationship between the expected value of change in the response variable y and the value of the regressor x changed by 20 or 40 units. Describe the condition or assumption, if any, to meet for such exploration. 3. In a multiple linear regression model where x1 and x2 are two regressors. Explore the relationship between the expected value of change in the response variable y and the value of the...
Answer both questions please true or false 16. The slope of the simple linear regression equation represents the average change in the value of the dependent variable per unit change in the independent variable (X). True/False 19. When using simple regression analysis, if there is a strong correlation between the independent and dependent variable, then we can conclude that an increase in the value of the independent variable causes an increase in the value of the dependent variable.
Suppose we fit the simple linear regression model (with the usual assumptions) Y = Bo+B1X+ € and get the estimated regression model ♡ = bo+bix What aspect or characteristic of the distribution of Y does o estimate? the value of Y for a given value of X the total variability in Y that is explained by X the population mean number of Y values above the mean of Y when X = 0 the increase in the mean of Y...
