During the PVC batch suspension process, the determinant characteristic of the PVC is given by Kw = f(T^∘
, m_in) where Kw is the so called Kwert, T^∘
is the reaction temperature, and min is the total mass of initiator. The experimental data measured in the process are given in Tab. 3.7.

Calculate the regression coefficients of the following types:

and discuss which model is the most appropriate to describe the measurements.
