As the figure shows, the maximum error from the simplified model in our example is about 1.25°C, the RMS error is probably<br />
closer to 1/2°C.<br />
For comparison let’s look at the full model without the squared term, namely<br />
Ln r A B<br />
<br />
T D<br />
<br />
T3 Fitting this model to our truth model yields<br />
