I have this series:
r <- c(14.1649994,17.3997831,32.8877030,6.1547551,6.3594748,101.9584077,196.8411517,23.8292043,11.7583992,2.2915478,5.5088687,16.8188390,2.3077979,2.6666377,2.0955362,0.9319688,0.6688078,1.0523184,6.8158264,13.1813211,17.8467944,1.9876636,7.0219306,3.9272217,4.3325448,7.8778125,1.1878058,1.7207762,2.9655665,5.8571428)
I'm using the
strucchange package to detect the structural changes. The result is:
> sctest(r~1) Recursive CUSUM test data: r ~ 1 S = 0.7785, p-value = 0.1579
How is it possible that the test didn't detect changes? There is a very big move rising around 200.
Take a look at the plot of the series below.
