Which of the following are true in simple linear regression? True or False for each

  1. There is only one independent variable (X).
  2. Y is the dependent variable.
  3. The relationship between X and Y is described by a linear function.
  4. Changes in Y are assumed to be related to changes in X.
  5. X is the independent variable because Y is dependent on X

What are the pitfalls of simple linear regression? True or False for each Lacking an awareness of the assumptions of least squares regression. Not knowing how to evaluate the assumptions of least squares regressions. Not knowing the alternatives to least squares regression if a particular assumption is violated.

Which of the the following are true regarding regression models? Select all that apply. Group of answer choices Errors sum to a large number. The relationship between the dependent variable and independent variables must be non-linear. It is used to determine if one or more independent variables affect the dependent variable. The error is found by subtracting the actual value from the predicted value. Observations must be independent.
