Choosing right statistics,regression method

[Milentije]

I have a crooked line of data points,want to project data on the straight line.If I go standard least-square method,some of the points change their position to each other,this is not want I a want.Anyone has idea about regresion methods or some other statistics,except classical y=bx+c.

Hey Milentije.

What do you mean by change their position to each other? Can you describe this (or perhaps provide a picture)?
