Question
Report the Error Degrees of Freedom for this example:
Assume you have 150 observations:
You create a first order model with 4 different numerical explanatory variables.
What are the Error Degrees of Freedom?_______
Report the Error Degrees of Freedom for this example:
Assume you have 150 observations:
You create a model with 2 numerical explanatory variables both with a linear relationship to the response and 1 categorical explanatory variable. The categorical variable has 4 levels.
What are the Error Degrees of Freedom?_____
Report the Error Degrees of Freedom for this example:
Assume you have 150 observations:
You create a model with 1 numerical variable that incorporates a quadratic relationship to the response, 1 numerical variable with a linear relationship and 1 categorical variable with 2 levels.
What are the Error Degrees of Freedom?______
Report the Error Degrees of Freedom for this example:
Assume you have 150 observations:
We create a model with 2 numerical explanatory variables both with a linear relationship to the response. In addition there is one categorical variable with 3 levels and another categorical variable with 4 levels.
What are the Error Degrees of Freedom?______
Explanation / Answer
Report the Error Degrees of Freedom for this example:
Assume you have 150 observations:
You create a first order model with 4 different numerical explanatory variables.
What are the Error Degrees of Freedom?_______
150 - 4 = 146
Report the Error Degrees of Freedom for this example:
Assume you have 150 observations:
You create a model with 2 numerical explanatory variables both with a linear relationship to the response and 1 categorical explanatory variable. The categorical variable has 4 levels.
What are the Error Degrees of Freedom?_____
150 - 2*4 = 142
Report the Error Degrees of Freedom for this example:
Assume you have 150 observations:
You create a model with 1 numerical variable that incorporates a quadratic relationship to the response, 1 numerical variable with a linear relationship and 1 categorical variable with 2 levels.
What are the Error Degrees of Freedom?______
150 - 2*1 = 148
Report the Error Degrees of Freedom for this example:
Assume you have 150 observations:
We create a model with 2 numerical explanatory variables both with a linear relationship to the response. In addition there is one categorical variable with 3 levels and another categorical variable with 4 levels.
What are the Error Degrees of Freedom?______
150 - 2*3 =144
