Suppose we collect some data that generates the scatterplot above (where the response variable is on the y-axis and the explanatory variable is on the x-axis). Does this data appear to violate any of the assumptions of the linear regression model? If so, which one. linearity symmetric/unimodal residuals No/impossible to say without access to the raw data. constant variability.

Does the following residual plot indicate any violation of the regression assumptions? If so, which one? Predicted y values Zero-mean Constant variance Independence No violation
Roushan A.
Suppose that you generate a scatterplot of residuals versus fitted values of the dependent variable for an estimated regression equation. Furthermore, you find the correlation between the residuals and fitted values to be 0.829. Does this provide a good indication that the estimated regression equation is satisfactory? Explain why or why not.

This graph shows the observed response variable vs the predicted response variable (for a particular model). What is the correct interpretation? Observed vs. predicted 120000 90000 60000 30000 0 25000 50000 75000 100000 Predicted response variable. The model violates the assumption of linearity. The model violates the assumption of constant variation of the residuals. The model violates the assumption of nearly normal residuals. None of the assumptions of the linear model appear to be violated.
