Residual plot in Mathcad

[ptc-5137806]

Hi.

I have this plot in MATLAB:

And i have triede to plot the same function in Mathcad:

The points doesn't match. I think the problem is the xi value in the MATLAB code. How do i make exactly the same plot in Mathcad ?.

(x in Matlab is Y in Mathcad) and (t in MATLAB is X in Mathcad)

Hi Osman,

How are defined variables "x", "t", "gamma", "beta" in your MATLAB document?

Maybe more luck if you attach your Mathcad worksheet here and provide the informations VladimirN has asked for. A pdf-document showing the Matlab code could be an option.

My Mathcad document is also uploadet.

Thanks in advance

The Linear regression Graph in the Mathcad document matches exactly with the Linear regression plot in the MATLAB code. The only problem is the residual plot.
