A method and apparatus for data analysis according to various aspects of the present invention is configured to automatically select one or more outlier identification algorithms for identifying statistical outliers in test data for components. The method includes comparing, within a comparison module, a system video signal with the determined mathematical relationship to produce an adjustment signal. Each member is shaped and configured for fitment into a cavity defined by the raised and recessed portions of two abutting supports to connect the connecting strips of two PCBs via said conducting strips. 60 and an angle of repose of 30 to 50 degrees, and has a hardness of 7 to 20 kgf, when directly compressed. The system also has several layers of fault detection. A vdisk restore process duplicates the inode of a vdisk within the active file system and performs a reconciliation process between the blocks of the twin inode and the snapshot inode.
