PSTricks | Other than linear Fitting

Post by svend_tveskaeg »

Hi all.

Is it possible to plot data and their fit if the latter is anything other than a linear function (see section 12.4 of the pst-plot manual for this)?

Thank you in advance!

P.S. I have found this post but I cannot figure out if it has been implemented in a package. Herbert has asked if he could put it into pst-func but the manual tells nothing of this as far as I can see.

install http://texnik.dante.de/tex/latex/pst-fit/pst-fit.sty
and http://texnik.dante.de/tex/generic/pst-fit/pst-fit.tex

don't know why it is not on CTAN.

Sweet!

If you create a manual, please let us know. ;)

By the way, is it possible to print the expression for the fitted curve and the correlation coefficient in mathmode? Furthermore, can the order of the terms in the printed expression be reversed?

Thank you in advance.

sure, but it needs a rewrite of the macros ...

Okay. I will give it a try tomorrow and post what I come up with.

This is not exactly going well. :?

First: The data file data.dat is attached.

I have tried to alter line 805 from

Code: Select all

  PolyEq { (y =) show
to

Code: Select all

  PolyEq { ($y =$) show
but then I just get the output in the attached picture.

Update
If it is not trivial to convert the printed output in math mode and reverse the order of the terms, it is hereby a request for the next version of the package. ;)
