sample standard deviation around the regression line

A MATLAB “function” is a MATLAB program that performs a sequence of operations specified in a text file (called an m-file because it must be saved with a file extension of *.m). A function accepts one or more MATLAB variables as inputs, operates on them in some way, and then returns one or more MATLAB variables as outputs and may also The problem is your function regress, try using lm() for a linear model but there are also other functions you can try depending on your data (fitglme is one I use in psychology).

Similarly, F= g (f, T) could also be obtained. 5.1 Interface to univariate modeling When in MATLAB environment, the way to call the ﬁtting function of the package is11 : 1 Spec Out=MS Regress Fit(dep,indep,k,S,advOpt) The ﬁrst variable Spec Out is the output structure which contains all the information regarding the estimated model. regress is useful when you simply need the output arguments of the function and when you want to repeat fitting a model multiple times in a loop. If you need to investigate a fitted regression model further, create a linear regression model object LinearModel by using fitlm or stepwiselm. A LinearModel object provides more features than regress. X = splitapply(@regress(T.StockReturn,[T.Ones T.MarketReturn]),T,T.Groups); Best Answer First argument is just a function handle or an anonymous function -- you mixed metaphors by trying to call a function and call that a handle

A LinearModel object provides more features than regress. If the help function isn't enough, try the doc function, "doc regress" which will give you the full documentation on the regress function. Thank you very much for the response, I am using the 2012 version of Matlab. Matlab works by reading files in the search path. In order to use the functions of MS_Regress, all you need to do is to tell matlab to look for the files in the m_Files folder (e.g. addpath ('m_Files') of the zip file.

I think regress function is convenient. X=[ones(size(regressorX,1),1),regressorX]; b = regress(regressorY',X); The results are I am working on a regression problem. There are two commands in Matlab for doing multiple linear regression. They are 'regress' and 'fitlm'.
