Does the time series has to be seasonal adjusted or not ?
Yes, seasonal adjusted would be good,
@@geostadt578 thx
1. If I want to run model without log, but to find output gap I am using log, then I will get output gap in log. How to get with log output gap? 2. Also my variables are in rates, so I don't want to convert to %.
If i want to calculate the inflation gap, should the value of inflation be logged or not. Thanks
No log. Because the inflation is already a rate of change and measured in the same dimension as the output gap..
if i want to measure the output gap, should the value of log GDP transform to %?
Yes. The Dimension has to be the same for example 3% inflation gap or 2% output gap... The Dimension has to be the same
