stationarity

Hi, I badly need your help, plss)) I am trying to run a regression, but got stuck with the problem of stationarity. I have gdp growth (%) and inflation rates (annual % change of cpi index) in my equation which are not stationary. Is it right to take the first difference of this variables (d(gdp_grow...

output gap stationarity

Is it right to take the 1st difference of the "output gap" data? It is already a difference (difference between the actual output of an economy and its potential output) but the data series is not stationary. I have calculated the potential output by using HP filter. But I did not correct ...

I have collected all the quarterly data for the inflation rate for my sample period (can't I still use HP filter?). Anyway, I've better use low-to-high frequen...

Hodrick Prescott Filter

I need to get quarterly data on inflation targets set by central banks, but those are normally set on annual basis. Is it possible to estimate those banchmark rates (inflation targets) using Hodrick Prescott Filter based on the inflation's quarterly data ? Or I need to use linear interpolation in or...
