Learn four methods to test the goodness of fit for a nonlinear regression model: residual analysis, R-squared, information criteria, and likelihood ratio tests.

For example, under the assumption of normal error, accurate or optimal tests can be obtained in many cases. A typical example is the goodness-of-fit test of regression function (See ref. [1] [2] [3]).

Freshwater is the planet’s most important natural resource and is prone to pollution, making it necessary for real-time monitoring. The Internet-of-Things (IoT)-enabled water quality monitoring (WQM) ...

In this work, we introduce a structured regression approach to disaggregated evaluation that we demonstrate can yield reliable system performance estimates even for very small subgroups. We provide ...
