The sequential supF(l+1:l) tests selects two breaks (i.e., m=2), the BIC selects m=5, and the LWZ selects m=4.
The BIC and the LWZ both select m=8, and the supF test selects 10.
So, to select the number of breaks we compute the BIC and for comparison the LWZ. Figure 2 shows the values of these two criteria for the number of breaks from 1 through 30.
These breaks are detected by both the BIC and the LWZ criteria.

In addition, the LWZ.3 offers an aperture range of T2.9-22 with 11 iris blades, and comes with the Interchangable Mount System (IMS), which makes it easier for users to adapt the lens to their current camera systems.
The LWZ.3 also addresses the need for affordable, high-quality manual lenses, at a time when camera offerings continue to broaden the range of video applications, according to Victor Cheang, regional sales director, South-east Asia and ANZ, ZEISS.
He said: "The new ZEISS LWZ.3 can fulfil this need--one zoom at an affordable price to fit all situations with its ideal range of focal lengths, meeting major film set requirements of budget-conscious productions.
"The compactness and range of focal lengths allow the use of the ZEISS LWZ.3 as a single lens for a wide range of assignments, with a high variety of sceneries."
Because of a combination of attractive features--range, modern optical design in a compact and high-quality housing that provides superior image performance in any imaginable shooting situation, as well as affordable price--the ZEISS LWZ.3 is a long-term investment, especially for smaller productions.
Our cine lenses--the Compact Prime CP.2, Compact Zoom CZ.2, and Light Weight Zoom LWZ.3--have a good range of coverage from Super 35mm to full-frame sensors.
The new ZEISS LWZ.3 can fulfil that--one zoom at an affording price to fit all situations with its ideal range of focal length, meeting major film set requirements of budget-conscious productions.
