Hello I have the following problem:
z=a+bx+cy I have a xyzdataset and i need to find a,b,c parameter.
I have no idea to solve this problem.
Sould I have to do 'nonlinear implicit curve fit'? Or should I have to do 'multiple linear regression'? Then, should I need to set my 'x, y, zdataset' as 'x1, x2, ydata' ???? Or should I need to set my 'x, y, zdataset' as 'x, y, zdata' ???? should I need to set function type as 'equations : f=a+bx+cyz' ??? Or should I need to set fuction type as 'LabTalk Scrip'??? But I have no idea to make a script.
Also, I followed this post and I tried a lot AND failed. (POST: https://my.originlab.com/forum/topic.asp?TOPIC_ID=1734 )
Please help me. This problem is killing me. Please... Help me ASAP... Also, if you have something misunderstand, I wil explain. Thank you so much. Have a good day.

Hi, Shirley Tian
Thank you for your reply. I understood about nonlinear cureve fit.Thank you so much.
Well, I am wondering about..... what kind of 'FUNCTION TYPE' to choose.
Can you answer me what kind of 'FUCTION TYPE' I should choose? After that, how do I set up the equation (or script or sth else)?
I'm in a bit of a hurry. Please answer me ASAP. Thank you.
