I must apologize for my bad English.
I have Mathcad PLUS 6.0. I'm trying to get a linear and a parabola regression for a few values for x- and y-axis. I tried to adapt the help, but it's using 3 dimensions. I think I know how to use regress, but I don't understand, how to handle interp.
I also have cases, in which I should force the curve through the origin and put simple units near the axis. I expect that those units can be found in the menus so I don't have to make them up.
I would appreciate it, if someone made it so easy for me, that all I have to do is to give the values and the units, decide if the regression was linear or parabola and if the regression should be forced through the origin.
You're my last hope. Please help me.
