the determination of confidence intervals in linear regression (Chapter 8), and computer codes using commercial software such as MATLAB and MATHCAD.

Fit a linear regression model that contains a categorical predictor. Reorder the categories of the categorical predictor to control the reference level in the model. Then, use anova to test the significance of the categorical variable.

The coefficients from the linear fit, referred to as volume fractions, were also analyzed.

In this video, I will show you how to import data file in matlab, and fit it with a linear equation using matlab inbuilt polyfit function. In this method yo

It estimates the parameters as ‘P’ , and then calculates a regression line in ‘LinFit’ .

Compare Fit of two linear models. Learn more about compare fit, model fit, goodness of fit I think both JDilla and Benjamin were talking about the so-called "Segmented regression" or "broken line regression". If it is for line fit, then "Segmented regression" becomes "Segmented linear regression". The "2003.5" number mentioned by JDilla is the so-called "breakpoints" which I think is quite subjected to personal decision.
