Dear all:
when i use bayesian esimation method to estimate some parameters using quartly data, and i get errors following that:
Log data density [Laplace approximation] is NaN.
I don’t know how to solve, what is the problem？
I wonder whether is the data problem, and the procedure i handle the data following that:(1)seasonal adjustment to get the trending and cyclic data;(2) then use the logarithmic form for the data;(3) use hp filtering to get the cyclic data, is the procedure right?
And the last question is how to judge the bayesian estimation results or how to judge the model is good or bad?
Hope for your help, thank you!!
