I'm trying to understand the concept of degrees of freedom in the specific case of the three quantities involved in a linear regression solution, i.e. SST = SSR + SSE, i.e. Total sum of squares = sum of squares due to regression + sum of squared errors, i.e. ∑ (yi − ˉy)2 = ∑ (ˆyi − ˉy)2 + ∑ (yi − ˆyi)2. I tried Wikipedia and ... Webwhere SST = SSR + SSE. Given these definitions, R-square is expressed as. ... the number of independent pieces of information involving the n data points that are required to calculate the sum of squares. Note that if parameters are bounded and one or more of the estimates are at their bounds, then those estimates are regarded as fixed.
