ACER ConQuest 5 新版特色
ACER ConQuest 5 is a computer program for fitting both unidimensional and multidimensional item response and latent regression models. It provides data analysis based on a comprehensive and flexible range of item response models (IRM), allowing examination of the properties of performance assessments, traditional assessments and rating scales. ACER ConQuest 5 also offers wider measurement and research community analysis procedures based on the most up-to-date psychometric methods of multifaceted item response models, multidimensional item response models, latent regression models and drawing plausible values.

ACER ConQuest Version 5 software includes:

• A choice of marginal maximum likelihood, joint maximum likelihood or Bayesian Markov Chain Monte Carlo (MCMC) estimation
• With MCMC estimation, the ability to add random effects to the item response model
• Implementation of multidimensional and multifaceted Bock model and generalised partial credit model (GPCM)
• Estimation of the Bradley–Terry–Luce (BTL) model for pairwise comparisons
• Direct reading of SPSS data files and CSV text files
• Output of results to SPSS, EXCEL, CSV or other text files
• A wide array of graphical outputs, including Wright maps, Wright predicted probability maps, likelihood plots and information maps
• Person fit and residuals
• Latent variable path modelling
• Mantel-Haenszel DIF estimates
• Powerful manipulation of matrix variables and control logic (if, while, do) for advanced modelling, including specifying custom design matrices or fitting iterative models.
• Integration with R through the conquestr library
• Advanced features, including the ability to impose new constraints on GPCM models, including imposing maximum and positive scores, as well as freely estimated variances through slope constraints.
