What is the goal of nonlinear regression fitting? Why would one choose nonlinear regression over linear regression of a linearized model function? Do you need to provide initial guesses for the model parameters in linear regression? In nonlinear regression? Explain the differences. Can someone help me answer these questions? This is for a design of experiments class. I just want to make sure that I fully understand this stuff because the explanations online are slightly misleading.

When fitting a multiple regression model, you should check for independence of observations and the absence of multicollinearity. Discuss how you would check appropriate statistics and/or plots. (a) When we run a multiple regression, we hope to be able to generalize the sample model to the entire population. To do this, several assumptions must be met including:  No Multicollinearity  Homoscedasticity  Independent Errors  Normally-distributed Errors Explain what is meant by each of these assumptions and describe the...
