First make the subjects give either right or wrong responses to the same question with different b value. When estimating the abilities of the subjects with the use of one-parameter or two-parameter Logistic model, it is found that there exists two kinds of unfits.(2) Estimate the abilities of the subjects after introducing c parameter on the basis of the two-parameter model. The first unfit can be rectified. However, the second unfit still exists and the third unfit appears.(3) Then estimate again after introducing y parameter. It is discovered that the second unfit is rectified, but the first unfit still exists and the fourth unfit appears.(4) Form Logistic four-parameter model by introducing c parameter and y parameter at the same time and estimate one more time. This model makes all kinds of unfits, including the first, second, third and fourth unfits, rectified.
1设计这批被试分别做对或做错一道b值不同的试题,用Logistic单、双参数模型对被试进行能力估计时,发现被试能力估计存在着两类失拟现象;(2)在双参数模型基础上增加c参数,对被试进行能力估计,发现c参数能有效纠正第一失拟现象,然而仍然存在第二失拟现象,同时还存在第三失拟现象;(3)在双参数模型基础上增加γ参数,再对被试进行能力估计,发现γ参数能有效纠正第二失拟现象,而仍然存在第一失拟现象,同时还存在第四失拟现象;(4)同时增加c、γ参数形成Logistic四参数模型,再对被试进行能力估计,这时该模型对各类失拟现象,包括第一、第二、第三、第四失拟现象都具有良好拟合能力。
