In this thesis, based on item response theory, a number of ways to estimate the latent trait and item parameters were introduced and their advantages and disadvantages were analyzed ; what is more, empirical logistic regression and two parameters logistic model ( 2plm ) are combined to set up a linear model by logit - mapping and a new parameter - estimation method is proposed
新方法將經驗logistic回歸用於兩參數logistic模型的參數估計,使用logit變換建立線性模型,利用線性模型的最小二乘估計得到第j個項目的項目參數向量_ j = ( _ j , _ j )的兩步估計由於x _ j含有未知的討厭參數,的理論值也和有關,我們結合上式的結果對進行再估計。
