A new technique, nonlinear logistic regression, is described for modelling binomially distributed data, i.e., presence/absence data where growth is either observed or not observed, for applications in predictive food microbiology. Some examples of the successful use of this technique are presented, ...
Nonlinear data is found where there is not a consistent value pattern or proportion between two variables. Learn the steps of transformations involved in making nonlinear data more manageable, and practice different types of transformations through example problems. Create an account Table of Contents...
This tutorial covers many aspects of regression analysis including: choosing the type of regression analysis to use, specifying the model, interpreting the results, determining how well the model fits, making predictions, and checking the assumptions. At the end, I include examples of different types...

1.6: Nonlinear Regression for Multi-OutputsOne of special features of Auto2Fit is it capable of doing regression for the problems with more than one dependent variable. In the following example, there are three independents: X1, X2 and X3, two dependents: Y1 and Y2, and four parameters a...
Inappropriate functional form: by formulating a different regression model (where the variables are transformed through nonlinear functions), the variance of the error terms would decrease considerably. When these problems are present, there may exist a better regression model than the one we have chos...
Anonlinearrelationship can be seen by scatter plots on a graph following a certain pattern but that pattern is not linear, meaning the representation is not a straight line. What Is an Example of a Linear Relationship in Statistics? An example of a linear relationship would be an hourly-paid...
