Suppose the residuals in a residual plot in simple linear regression show a curved pattern. Here are three statements. I. This means the relationship between the explanatory and response variable is non-linear. II. This means there is non-constant variation of the residuals. III. This means the residuals are not normally distributed. Which of the above statements is true? Select all that apply. A. I. This means the explanatory and response variables are non-linearly related. B. II. This means there is non-constant variation of the residuals. C. III. This means the residuals are not normally distributed. D. None of the above.

A curved pattern in the residuals can indeed suggest a non-linear relationship between the explanatory and response variable. So, statement I is true and option A is correct. II. A curved pattern in the residuals can also suggest non-constant variation of the Show moreā¦

In the context of regression analysis, which of the following statements are true? I. When the sum of the residuals is greater than zero, the model is nonlinear. II. A random pattern in the residual plot indicates that linear regression is appropriate. III. Influential points always reduce the correlation coefficient. (A) I only (B) II only (C) III only (D) I and II (E) I, II, and III

In determining whether or not the underlying assumptions in simple linear regression are true, which of the following statements is / are true? I. If a residual plot has residuals that appear to be random, then it is okay to assume that there is a linear relationship between the predictor and the response variables. II. If a residual plot has residuals that are close to a straight, diagonal line, then the normality assumption is true. A. I. only B. II. only C. Neither I. nor II. D. Both I. and II.

Shown below are two plots of residuals remaining after fitting a linear model to two different sets of data. a) Describe important features and determine if a linear model would be appropriate for these data in (a). Choose all answers that apply. There is higher variability with larger x There is higher variability with smaller x A linear model would be appropriate A linear model would not be appropriate b) Describe important features and determine if a linear model would be appropriate for these data in (b). Choose all answers that apply. The residuals are a random scattering A linear model would not be appropriate A linear model would be appropriate The residuals show a pattern
