The generation of a Regression Equation is justified when we _____________. (Note: There are 4 correct answers).
Generating a regression equation is justified when we expect the relationship between the output and inputs to be linear, as regression analysis assumes a linear correlation. It is also useful when we need to understand how to control a process output by controlling the inputs, as regression can help model the relationship between these variables. However, knowing there is a non-linear relationship suggests a different type of analysis might be needed, and addressing process defects or timing/cost issues in measuring outputs are not direct reasons to justify generating a regression equation.
A. Expect the relationship to be Linear between the output and inputs C. Need to understand how to control a process output by controlling the input(s) D. Experience several process defects and have no other way to fix hem E. When it is very expensive or too late to measure the output
