Design–Expert is a statistical software package from Stat-Ease Inc. that is specifically dedicated to performing design of experiments (DOE). Design–Expert offers comparative tests, screening, characterization, optimization, robust parameter design, mixture designs and combined designs. Design–Expert provides test matrices for screening up to 50 factors. Statistical significance of these factors is established with analysis of variance (ANOVA). Graphical tools help identify the impact of each factor on the desired outcomes and reveal abnormalities in the data.
Methods and devices for automatic generation and evaluation of psychological scales for a target population
This invention belongs to the field of healthcare informatics, specifically relating to a method and apparatus for the automatic generation and evaluation of psychological scales for different subject populations. The method is based on expert-designed expert factors, utilizing a large-scale model to perform semantic analysis and structural induction on existing psychological scales, extracting psychological constructs and construct dimensions to form a knowledge base of psychological scale items. Based on this knowledge base, and given the scale design requirements such as target psychological constructs and subject population characteristics, the method combines the item knowledge base with the structural validity constraint mechanism of the expert-designed psychological scales to achieve the generation of customized psychological scales for different subject populations. Furthermore, it proposes a multi-dimensional automatic evaluation system for psychological scales that meets psychometric requirements, covering multiple different dimensions, providing feedback information for scale content optimization, and realizing the transformation of psychological scales from manual design to automated and controllable generation.
