Dear SAS experts,
I would like to know what is difference between estimation and calibration.
For example, for nonlinear regression model, we use data to estimate parameter values.
proc NLIN data=China_Q;
parms alpha=0.01 rho=0.01 beta1=0.01 beta2=0.01 beta3=0.01;
bounds alpha rho beta1 beta2 beta3 >= 0;
restrict beta1+beta2+beta3 = 0;
model Q = log (alpha) + rho*T + beta1*K + beta2*L + beta3*E;
In this case, this code is for estimation of parameter values in the nonlinear regressions model.
If I want to calibrate parameter values for this model, then I would like to know how to calibrate parameter values.
If you have any references/examples to explain the difference between estimation and calibration, please share them with me.
Thank you very much in advance.
