Breakpoint Unit Root Test
This view carries out unit root tests which allow for a structural break in the trend process (Perron, 1989). EViews offers support for several types of modified augmented Dickey-Fuller tests which allow for levels and trends that differ across a single break date. You may compute unit root tests with a single break under various specifications for the break.
See “Unit Root Tests with a Breakpoint” for details.
