This document outlines new functionality, system requirements, installation procedures, and descriptions of the documentation included with the NI Vision Development Module. The NI Vision Development Module is for engineers and scientists who are developing machine vision and scientific imaging applications. The NI Vision Development Module includes NI Vision and NI Vision Assistant. NI Vision is a library of powerful functions for image processing, and is available for LabVIEW, LabWindows™/CVI™, and Microsoft Visual Basic. NI Vision Assistant is an interactive environment for developers who need to quickly prototype vision applications without programming. In addition, the NI Vision Development Module ships with the NI Vision Acquisition Software CD, which includes National Instruments driver software for controlling image acquisition products.

The evaluation of assessment dimensionality is a necessary stage in the gathering of evidence to support the validity of interpretations based on a total score, particularly when assessment development and analysis is conducted within an item response theory (IRT) framework. Unidimensionality refers to the existence of one underlying measurement construct (dimension) that accounts for variation in examinee responses. Violating this assumption could severely bias item and ability parameter estimation. In this study, we employ polytomous item responses to compare two methods that have received increased attention in recent years: Rasch model analysis (Rasch, 1960/1980) and Parallel analysis (Horn, 1965) with TETRAD (Glymour, 1982), a method for evaluating assessment structure that is less well-known in the educational measurement community, though confirmatory TETRAD analysis has been developed by Bollen and Ting (1993, 1998, 2000) for identifying causal indicators.
