Minimum Dimension Analysis MDABehaviormetrika - Tập 1 - Trang 1-24 - 1974
Chikio Hayashi
In the present paper, the method of minimum dimension analysis (MDA) is given with examples. This method belongs to the same genre as smallest space analysis (SSA) by L. Guttman. Let Rij be the relation between i-element and j-element, i, j = 1,2,..., N. If Rij is given in the form of rank order, SSA gives the configuration of the elements with less inconsistancy in Euclidean space having smallest...... hiện toàn bộ
Bayesian Hierarchical Analysis of Polychotomous Item ResponsesBehaviormetrika - Tập 27 - Trang 51-65 - 2000
Kazuo Shigemasu, Osamu Yoshimura, Tomoyasu Nakamura
The Bayesian hierarchical model for polychotomous item responses and the Bayesian method for inferences of the parameters in this model were proposed using the Gibbs Sampler. The model is complex but reflects psychological reality. The method was applied to 40 sets of simulated data and its efficiency in estimation was compared to other established methods. The same method was also applied to the ...... hiện toàn bộ
Emerging methods for conceptual modelling in neuroimagingBehaviormetrika - Tập 44 - Trang 117-133 - 2016
Hiroyuki Akama, Brian Murphy
Some open theoretical questions are addressed on how the mind and brain represent and process concepts, particularly as they are instantiated in particular human languages. Recordings of neuroimaging data should provide a suitable empirical basis for investigating this topic, but the complexity and variety of language demands appropriate data-driven approaches. In this review we argue for a partic...... hiện toàn bộ
Interpolation of missing swaption volatility data using variational autoencodersBehaviormetrika - - Trang 1-27 - 2023
Ivo Richert, Robert Buch
Albeit of crucial interest for financial researchers, market-implied volatility data of European swaptions often exhibit large portions of missing quotes due to illiquidity of the underlying swaption instruments. In this case, standard stochastic interpolation tools like the common SABR model cannot be calibrated to observed volatility smiles, due to data being only available for the at-the-money ...... hiện toàn bộ
Collaborative Filtering for Massive Datasets Based on Bayesian NetworksBehaviormetrika - Tập 35 - Trang 137-158 - 2008
Maomi Ueno, Takahiro Yamazaki
This paper proposes a collaborative filtering method for massive datasets that is based on Bayesian networks. We first compare the prediction accuracy of four scoring-based learning Bayesian networks algorithms (AIC, MDL, UPSM, and BDeu) and two conditional-independence-based (Cl-based) learning Bayesian networks algorithms (MWST, and Polytree-MWST) using actual massive datasets. The results show ...... hiện toàn bộ
Construction of a System Dynamics Model by Principal Component AnalysisBehaviormetrika - - 1980
Masanori Nakagawa, Seiji Ohsawa
In the present paper we present a method of constructing a system dynamics model. When multiple variables are given, we sum them up by principal component analysis. By utilizing the extracted principal components we construct simultaneous differential equations concerning the original variables. Our method has two characteristics. First, usual factor analysis, etc., are restricted to the estimatio...... hiện toàn bộ
Empirical evaluation of fully Bayesian information criteria for mixture IRT models using NUTSBehaviormetrika - Tập 50 - Trang 93-120 - 2022
Rehab AlHakmani, Yanyan Sheng
This study is to evaluate the performance of fully Bayesian information criteria, namely, LOO, WAIC and WBIC in terms of the accuracy in determining the number of latent classes of a mixture IRT model while comparing it to the conventional model via non-random walk MCMC algorithms and to further compare their performance with conventional information criteria including AIC, BIC, CAIC, SABIC, and D...... hiện toàn bộ
