Who can help me in finding the right fitted-value-function?Based upon a linear model (2-dimensional, 1 result-variable and 1 input-variable). I found the perfect regression model (not always simply linear) by the function lm(). Based on the given input and output tuples. For these exact input values I can get the exact fitted values by the function fitted.values. The problem is, once I want to extrapolate with the automaticly found function (not always the same) and new input-variables I don't know how to calculate automaticly the fitted values. I don't know how to use the fitted values function with a given function and given input-variables but yet unknown result-values. Who can help me get the right fitted value function and tell me how to use it. Thanks in advance for any help.
