example. Use Matlab regress function X = [x ones(N,1)]; % Add column of 1's to include constant term in regression a = regress(y,X) % = [a1; a0] plot(x,X*a, 'r-'); % This line perfectly overlays the previous fit line a = -0.0086 49.2383 Multiple regression using weight and horsepower as predictors example. [b,bint,r,rint] = regress (y,X) also returns a matrix rint of intervals that can be used to diagnose outliers. example.
I believe a worked example like this question will greatly help the future readers. So I post it anyways. For example, if X is a 20-by-5 design matrix, then beta is a 5-by-1 column vector. If you specify X as a cell array containing one or more d-by-K design matrices, then mvregress returns beta as a column vector of length K. For example, if X is a cell array containing 2-by-10 design matrices, then beta is a 10-by-1 column vector.

I have a dataset comprising of 30 independent variables and I tried performing linear regression in MATLAB R2010b using the regress function.

Linear Regression Example This document is a matlab notebook, so if you open it with a computer that has matlab you should see a 'notebook' menu above that lets you execute the matlab commands in this notebook. % perform logistic regression (here we use the MATLAB function glmfit.m % instead of the direct implementation shown in Example 1) X = [classA(1,:)' classA(2,:)'; classB(1,:)' classB(2,:)']; y = [zeros(size(classA,2),1); ones(size(classB,2),1)]; paramsA = glmfit(X,y,'binomial','link','logit'); outputimageA = glmval(paramsA,gridX,'logit'); Demonstrates how to model a curve and perform regression in Matlab.
