| Video Discription | In this video I explain what is a degree of freedom. I jump into how data is free to move, this freedom becomes more limited after you apply a statistical model. We explore the relationship of model complexity and the degrees of freedom of the data. I explain how the more complex the statistical model is the less truly free the data is to vary. This lack of degrees of freedom undermines the predictive utility of model and that is disappointing to Karl Popper. Finally, we discuss the balance of explained variation, degrees of freedom and statistical power. Learning objectives Understand the concept of degrees of freedom Explain what happens to degrees of freedom when statistical models are applied to the data Discuss the relationship between degrees of freedom, model complexity, explained variation and statistical power [c07kg27SozE] |
