Dear R users,
i am wondering if anyone has some hints for this problem (i have not found a
clear answer after searching the R-mailing list archive, 'help.search' in R,
and R-Wiki, and the like...):
let's assume that i have 4 periods compositional time series data:
t=1, A=0.1; B=0.5; C=0.4
t=2, A=0.2; B=0.4; C=0.4
t=3, A=0.5; B=0.3; C=0.2
t=4, A=0.4; B=0.3; C=0.3
t=5, ???
By using R, could anyone suggest how to obtain the forecasted value of the
fifth period (t=5) as well as the forecast error? (it seems that 'mixeR'
[M.Bren] and 'compositions' [v.d.Boogart] have not provided a 'direct' solution
to this problem...)
really appreciate your time/help for this,
Thank you very much,
Sincerely,
hendry raharjo
