items parameters meaning in Chinese
项目的参数
Examples
- Development program for estimating item parameters in gpcm
模型项目参数估计程序的开发与研究 - A research of the test validity of the item parameter effect
运用项目参数调节测验效度的试验研究 - Item parameter and person ability estimate for continuous irt model with connectionism
模型的项目参数和被试能力估计 - The least square estimation in linear model is used to derive the two - stage estimation of the item parameter vector 1 of j th item as follows : noting that xj consists of the nuisance parameters s , j , j , were updated so that the estimation of 6 s could be renewed
修正进而修正x _ j和，从而形成一种新的估计方法?双重两步迭代估计蒙特卡洛模拟结果显示，双重两步迭代估计提高了估计对真值的恢复能力。 - 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
新方法将经验logistic回归用于两参数logistic模型的参数估计，使用logit变换建立线性模型，利用线性模型的最小二乘估计得到第j个项目的项目参数向量_ j = ( _ j ， _ j )的两步估计由于x _ j含有未知的讨厌参数，的理论值也和有关，我们结合上式的结果对进行再估计。
