Graphing the result of a regression in Matlab

Hi,

The results of my regression are as follows:

xt = 0.001 + 0.49xt-1 + 0.046yt + 0.11zt

I am trying to draw a simple graph to show these results. I have tried using explot and polyval/polyfit, but I can't get it to work out.

Any suggestions?

Many thanks.

Are xt, yt, and zt arrays where t is time and so they are arrays where each element is a different time point? Why is xt on both sides of the equation? Or is it really something like this:

x(t) = 0.001 + 0.49 * x(t - 1) + 0.046 * y(t) + 0.11z(t)

and you have this in a loop over t so that a given x depends on the prior x element and the current y and z elements? Can you supply typical values for x(1), and yt and zt?

You are missing all the '*' product signs between your polynomial coefficients and the variable; wrong MATLAB syntax doesn't get you what you want.

You probably want to read a MATLAB tutorial.
