英文縮寫MAR的擴展資料
- We develop imputation estimators of mean of responses for semiparametric varying-coefficient model with response variables missing at random.在響應變量隨機缺失時,研究了半參數變系數模型響應變量均值的借補估計。
- We present a framework for fitting mixtures of multivariate t distributions when data are missing at random on the basis of maximum likelihood ( ML ) estimation.我們基于極大似然估計,利用期望最大化算法導出了有數據隨機丟失(MAR)時多維t混合分布的擬合框架。
- It is very important to divide the missing data into three manners : missing at random ( MAR ), missing not at random ( MNAR ) and missing completely at random ( MCAR ).將數據缺失方式劃分為隨機缺失,非隨機缺失與完全隨機缺失,這對于合理編寫缺失數據推估程序,正確選用估算方法有很重要的意義。
