The problem of a nonlinear relationship is detected in residual analysis by which of the following?
A)a cone pattern
B)an arched pattern
C)a random pattern
D)an increasing pattern
E)a decreasing pattern

Question

Quizplus · Accepted Answer

An arched pattern in the residual plot is a sign of a nonlinear relationship between the dependent and independent variables. The residuals should ideally be randomly scattered around zero in a linear relationship. The other patterns listed (cone, increasing, decreasing) do not necessarily indicate a nonlinear relationship.
