I have a modeled data set R_mod which is a dependent on 5 other variables. Individual relationship of R_mod with 5 independent variables are polynomial relationships. Now i want to fit measured data R_mea with modeled data R_mod by adjusting 5 independent variables. Please suggest me how can perform this...i have another question as there will be infinite number of solutions to this problem how can i pick the reasonable solution.....thanks in advance...

Many things to think about... I suppose you could try linear regression, extract the coefficients, and compare them to what your model produces.

You should check that the predictors aren't correlated, otherwise your coefficients will be junk (/www.graphpad.com/articles/Multicollinearity.htm)
