# Identify changepoints in 1/0 sequence [duplicate]

Say I have a sequence that looks like this:

0 0 0 0 0 1 0 0 0 0 1 0 1 1 1 0 0 0 0 0 0 0 0 0 0


In general terms, I am interested in determining when there is an over-abundance of 1's in close proximity. Not necessarily in a row, but within a sliding window. In this example, the 0's and 1's represent whether a system is stable or unstable at regular time intervals.

Currently, I don't have any fixed notion of what exactly should constitute a significant or meaningful change in the sequence from 0's to more 1's, I am trying to work that out from some exploratory analyses.

I appreciate that this is somewhat general - however, if anyone has any ideas as to what literature to look at I would be grateful.
