WebApr 19, 2013 · If you have the curve fitting toolbox installed, you can use fit to determine the uncertainty of the slope a and the y-intersect b of a linear fit. Note: x and y have to be column vectors for this example to work. cf = fit (x,y,'poly1'); The option 'poly1' tells the fit function to perform a linear fit. The output is a "fit object". WebThey are not referred as mean, standard deviation and df because the mean and the variance of this distribution depend on the three parameters. Also, they do not exists in some cases. Peter Flom is fixing the df but this can be considered as an unknown parameter as well. – user10525 Dec 12, 2012 at 21:25 1
