Bugs in BREAKLS

Postby svilen » Mon Dec 02, 2013 6:38 am

We found two bugs in BREAKLS.

1. It doesn't use the user specified breaks, but uses dates which are two years after the specified breaks.

Code: Select all

%f = "test_file"
close {%f}
wfcreate(wf={%f}) q 2000 2015

smpl 2001 2015
series s1 = nrnd
series s2 = nrnd
series s3 = nrnd

smpl 2002 @last
equation eq1.BREAKLS(method=user, breaks="2006q1 2011q4") s1 s2 s3

show eq1

2. With the code above try to change the method to sequential tests of single l+1 versus l breaks. If you use the GUI EViews crashes. But if you do it with code it doesn't crash:

Code: Select all

equation eq1.BREAKLS(method=seqplus1) s1 s2 s3


ps it seems that there is a typo on page 283 of EViews 8 Command and Programming Reference
-> breakls(method=user, breaks=”1990q1 2010q4”) m1 c @nv unemp

Thanks for the detailed description. We'll take a look.

[edit] - Fixed the crash and a related bug in the parsing of user-specified dates in some equations estimated with sub-samples. The fixes will appear in the next update. Sorry for the inconvenience.
