The difference between the two regression equations lies in what they represent. The equation
typically represents the fitted line for sample data, where
is the intercept and
is the slope derived from a sample. This equation is an estimate of the relationship within the sample population.
On the other hand, when discussing a full population, one would use the true parameters
and
instead of the sample estimates, frequently denoted as
. The transition from sample to population indicates a shift from estimation to actual parameters, reflecting a broader context.
