%description
Applying the family of the Bayesian Expectation-Maximization-Maximization
(BEMM) algorithm to estimate: (1) Three parameter logistic (3PL) model
proposed by Birnbaum (1968, ISBN:9780201043105); (2) four parameter
logistic (4PL) model proposed by Barton & Lord (1981)
<doi:10.1002/j.2333-8504.1981.tb01255.x>; (3) one parameter logistic
guessing (1PLG) and (4) one parameter logistic ability-based guessing
(1PLAG) models proposed by San Martín et al (2006)
<doi:10.1177/0146621605282773>. The BEMM family includes (1) the BEMM
algorithm for 3PL model proposed by Guo & Zheng (2019)
<doi:10.3389/fpsyg.2019.01175>; (2) the BEMM algorithm for 1PLG model and
(3) the BEMM algorithm for 1PLAG model proposed by Guo, Wu, Zheng, & Chen
(2021) <doi:10.1177/0146621621990761>; (4) the BEMM algorithm for 4PL
model proposed by Zheng, Guo, & Kern (2021)
<doi:10.1177/21582440211052556>; and (5) their maximum likelihood
estimation versions proposed by Zheng, Meng, Guo, & Liu (2018)
<doi:10.3389/fpsyg.2017.02302>. Thus, both Bayesian modal estimates and
maximum likelihood estimates are available.
