[Tachart] Linear regression

[pacific2]

Dear all
I have a set of data in a lineseries and I want to compute the parameters (a and b) of a linear regression (y= ax+b). I read (I don't remember where) that tachart have a buitin function that make it easy.

if I'm wrong I can of course built my own regression function.

regards

You can use LazStats for this.

Thanks Leledumbo
Impressive project. May be a litle bit complex for what I need at the moment but I keep the link. I certainly need to use it in a near future.

Just for information. The sources as availlable for windows does not compile with my lazarus version. I had to add in the matmanunit.pas unit the keeword "var" before the list of variable at the line 246 just above the public declarations. After that it compile well.

No, TAChart only has TFuncSeries that makes displaying of your functions easy.
I am open to suggestions and patches for extending TAChart in this direction :-)

Indeed. Why does not it use TAChart, I wonder?
