I am using the Strucchange package in R to test for structural change in

Is there any way where I can restrict the test to hold b2 constant and test for
values as the function arguments and it still happens at around nine
monthes, or about 270 loops through the for (i in dates) loop or around
500 calls to the ODBC connection. I say around since I can start the
