Y=x represents a slope of 1
The degrees of freedom in a regression model is 2 if the model that has 10 observations and 7 independent variables.
<h3>What is a degree of freedom?</h3>
The amount of rows of training data used to fit the model equals the degrees of freedom.
Total observation = 10
Number of independent variables = 7
Degree of freedom for regression = 10 – 7 - 1
= 2
Thus, the degrees of freedom in a regression model is 2 if the model that has 10 observations and 7 independent variables.
