MATLAB: Is there a “regress” function in Matlab R2014a

MATLABmatlab r20141

I am trying to link some datasets through multiple linear regression, but I cannot find the regress function, nor does it appear in help. Is there still such function?

Best Answer

Yes, but it is in the Statistics Toolbox, not base Matlab.

You can build a general model and use the backlash operator "\" to solve for the least squares coefficients or there are other tools in the Curve Fitting Toolbox as well if have it but not Statistics.

MATLAB: How to obtain the regression statistics for weighted least squares regression in MATLAB

The ability to retrieve diagnostic statistics for weighted least squares regression in "lscov" is not available in MATLAB.

In the Statistics and Machine Learning Toolbox, these statistics are available by using the "fitlm", "fitglm", and "fitnlm" functions.

MATLAB: Regression

Here is an example:

x = (1:20)';
y = 2 + 3*x + 7*rand(20,1);
model = fit(x,y,'poly1')
figure
plot(model,x,y)

The plot command here is an "overloaded" method for cfit objects (the output of the fit command). The documentation is here: http://www.mathworks.com/help/toolbox/curvefit/plot.html
