I want to calibrate some parameters to match some moments of data. in the literature, many authors fixed some parameters and calibrate the others to match moments or some ratios like K/Y. But I have no idea how to implement it. are there any examples to do it? thanks!
One example is at https://github.com/JohannesPfeifer/DSGE_mod/tree/master/RBC_baseline. It calibrates the model based on big ratios like I/Y.
