2012-06-20 Thread denissearchundia
HI 

i'm trying to detect breaks points in various flow time series, they all
contains  seasonality and trend
my question is :

i have to remove this seasonality and trend before apply the function
breakpoints du package strucchange??

another question, the function breakpoints is similar to de Pettit tests ?
or how does it realy works?

THANKS
