question on starting values

[Elderfield.A]

Hi,

Is there any difference between a) creating a coefficient vector using the command "coef" and then setting the values equal to desired starting values and b) using the command param?

Specifically, is

Code: Select all

coef(3) a a(1) = 0.1 a(2) = 0.5 a(3) = -1

treated differently to

Code: Select all

coef(3) a param a(1) 0.1 a(2) 0.5 a(3) -1

I am especially interested in the context of state space models, as the help page explicitly states using the "param" approach.

Thanks

Adam
