| Apr 27, 2023 at 12:21 | comment | added | whuber♦ | (Continued) I quote from that site, emphasizing the problematic assertions: " The SAS Nonlinear Regression implies curved relationships. In this, the dependent or criterion variables are modeled as a non-linear function of model parameters and one or more independent variables. The reason that these models are called nonlinear regression is that the relationships between the dependent and independent parameters are not linear." The remaining "tutorial" has so many usage errors that it smells very fishy. | |

In researching it, the "featured" Google hit looks like an official SAS page but is truly awful: it can't even maintain the distinction between variables and parameters! For the record, the site to avoid is data-flair.training/blogs/sas-nonlinear-regression. | |

| Jan 27, 2019 at 16:43 | comment | added | ColorStatistics | can you recommend a concise, introductory reading that will help me get a better sense of the linearization you mention, which is the heart of the difference between your example and non-example in point 5. Thank you. | |
