Dear list,
I would like to ask you a question. I'm trying to build the time series'
production with the Divisia index. The final step would require to do the
following calculations:
a)PROD(2006)=PROD(2007)/1+[DELTA_PROD(2007)]
b)PROD(2005)=PROD(2006)+[1+DELTA_PROD(2006)]
c)PROD(2004)=PROD(2005)+[1+DELTA_PROD(2005)]
my question is how can I tell R to take the value generated in the previous
step (for example is the case of the produciton of 2005 that need the value of
the production of 2006) in order to generate the time series production??
(PS:my data.frame is not set as a time series)
Thanks for your attention!!
