| Mar 26, 2016 at 20:39 | comment | added | IrishStat | When you state I din't want to do a "super analysis" you are implicitely asking for " a back of the envelope" quick'n dirty solution that is highly unlikely to be worth anything and will deliver on average a worthless result. There is no Santa Claus for you or this problem/opportunity just complexity and extracted/useful information gleaned from the data.. | |

| Mar 24, 2016 at 20:39 | comment | added | IrishStat | Everybody wants to do this (simply and probably incorrectly) . Detecting level shifts ( a form of change ) is important to your analysis. Detecting changes in trends ( a form of a change) is important to you. Both circumstances need to be robust to pulses or one-time anomalies and possible daily effects. All analyses need to be robust to the underlying auto-projective memory . Please post an example of one of your series and I will try and help. There is absolutely no quick/cheap/easy/basic/childlike procedure ... there is just a lot of deficient approaches BUT I will try and help. | |

| Mar 24, 2016 at 19:40 | comment | added | tchakravarty | Your context suggests that you would have a break in mean in the CPC time series, whereas you say that you want to discover a break in trend. These are two different things, and you should be clear on which one you want. | |
