I have a series of numbers that decrease by about the same percetentage rate with time. How do I do the regression to find the exact percentage rate it is changing? For example, it can be something like the belo
b = regress(y,X) returns a vector b of coefficient estimates for a multiple linear regression of the responses in vector y on the predictors in matrix X. To compute coefficient estimates for a model with a constant term (intercept), include a column of ones in the matrix X. example [b...

To begin fitting a regression, put your data into a form that fitting functions expect. All regression techniques begin with input data in an arrayXand response data in a separate vectory, or input data in a tabletbland response data as a column intbl. Each row of the input data represen...

Regression Technique Gives Bad CoefficientsI'm trying to perform an unfolding technique using regression techniques, and to be blunt, my abilities with matlab and with regression techniques in general is basic at best. I've tried using the lsqcurvefit command, but I'm running into one problem. ...
