Hello I've installed the package Holt 1.0 for trend estimation. I have two problems: 1. With gretl 1.10.2 for Mac with the system OS 10.11.4 installed I cannot use the function Holt's trend since gretl closes automatically. I select the variable and go to the menu Variable / Filter /Holt's trend and the program closes automatically. 2. The package works on Windows 10 but there is a difference between my calculations and the output windows. I choose for the starting data the OLS with first half of the sample I get L0 = 202.625 for the start level and b0 = -0.3682 for the start trend level. The first forecast is h^1 for the first period based on period 0: h^1 = L0 + b0 = 202.2568 With the gretl function I get 203.0051. Obviously there is a problem. Thank you for your feedback.
