Bai Perron and Trim factor

[strypste]

Hi there

I wanted to perform a Bai and Perron test with a trimming parameter of 25 and a maximum number of breaks equal to 5. My sample is 330 observations.

I get the following error message:

Invalid specification for the maximum number of breaks given the sample size and trimming percentage (must be less than or equal to 2)

With a trimming of 20 is also does not work. It only works if I use a trimming of 15 or lower.

Could somebody explain this or point me to some documentation about this?

Trimming percentage implicitly determines the minimum segment length permitted when constructing a test:
