The model for simple linear regression is

where
- Yi is the value of the
response variable in the ith trial
-
and
are
parameters that we will estimate.
- Xi is
a known constant, namely, the value of the independent variable in the ith trial
is
the random error term. For the general model, the error terms have a
mean of zero and constant variance. The commonly used Normal model
includes the additional assumption that the error terms are also normally
distributed. This is the model that we will use throughout this
tutorial.
- The
random error terms are uncorrelated.
