This chapter discusses the simplified linear and nonlinear regression analysis. The actual performance of a regression analysis involves a large number of numerical computations. Therefore, usually a computer w
Prism lets you enter XY data as mean, SD (or SEM) and N. Prism 5 and later If you analyze these data with ordinary nonlinear regression, Prism gives exactly the same results as if you had entered raw data, even with weighted regression. This document explains the mathematical details ...
R-squared is not valid for nonlinear regression. So, you can’t use that statistic to assess the goodness-of-fit for this model. However, thestandard error of the regression (S)is valid for both linear and nonlinear models and serves as great way to compare fits between these types of m...
Nonlinear regressioncan be a powerful alternative to linear regression because it provides the most flexible curve-fitting functionality. The trick is to find the nonlinear function that best fits the specific curve in your data. Fortunately, Minitab provides tools to make that easier. In theNonline...

What is the difference between linear and nonlinear regression equations? The fitted line plot shows that the regression line follows the data almost exactly -- there are no systematic deviations. It’simpossible to calculate R-squared for nonlinear regression, butthe S value(roughly speaking, the...

a straight line,nonlinear regressionmay be used instead. Linear and nonlinear regression both track a particular response from a set of variables. As the relationship between the variables becomes more complex, nonlinear models have greater flexibility and capability of depicting the non-constant ...

We should compute the correlation coefficient only for data that follows a linear pattern or to determine the degree to which a data set is linear. If the data exhibits a nonlinear pattern, the correlation coefficient for a linear regression is meaningless. To get a sense for the rela...
