I have a set of data, sampled once per year from 1990 to 2008. It looks more or less linear. However, doing a Chow test results in a significant p-value (0.003 and below), wherever I test for a structural break. What is going on?
(There was a similar question once before, but it didn't really receive a satisfactory answer.)
The p-value is very small wherever I test to see if there is a structural break.
An answer would be much appreciated!
