good evening! im new to state space, and i would like to ask the implication if we set the Clark model to the following specification: log_gdp = sv1 + sv2 @state sv1 = sv1(-1) + sv3(-1)+[var=exp(c(1))] @state sv3=sv3(-1) +[var=exp(c(1))] @state sv2 = c(1)*sv2(-1)+c(2)*sv4(-1)+[var=exp(c(1))] @state ...

what are the implications of a very large z-statistics? are there any solutions?
