Hi
Could just anyone explain me the coefficients in the output of arima model
The person who wrote the help page already did, but that is hardly 'just
anyone'.
timeseriesarima <- arima(series, order=c(1,1,2))
timeseriesarima
Series: series
ARIMA(1,1,2)
Coefficients:
ar1 ma1 ma2
0.9744 -1.7695 0.7873
s.e. 0.0310 0.0481 0.0426
sigma^2 estimated as 337.4: log likelihood=-1096.03
AIC=2200.07 AICc=2200.23 BIC=2214.2
That is not from arima in package stats, so you need to follow the
posting guide to tell us whose wrapper it is and hence which help page
to read. (Possibly package TSA.)
