Missingness in mixed-type variables is commonly encountered in a variety of areas. The requirement of complete observations necessities data imputation when a moderate or large proportion of data is ***, inappropriate imputation would downgrade the performance of machine learning algorithms, leading to bad predictions and unreliable statistical inference. For high-dimensional large-scale mixed-type missing data, we develop a computationally efficient imputation method, missing value imputation via generalized factor models（MIG）, under missing at random. The proposed MIG method allows missing variables to be of different types,including continuous, binary, and count variables, and are scalable to both data size n and variable dimension p while existing imputation methods rely on restrictive assumptions such as the same type of missing variables,the low dimensionality of variables, and a limited sample size. We explicitly show that the imputation error of the proposed MIG method diminishes to zero with the rate Op(max{n-1/2, p-1/2}) as both n and p tend to infinity. Five real datasets demonstrate the superior empirical performance of the proposed MIG method over existing methods that the average normalized absolute imputation error is reduced by 5.3%–34.1%.

用组织切片方法系统地观察了草鱼卵被经辐射处理的鲤精子激活后进行第一次卵裂的发育过程。实验表明 :在 2 4℃孵化水温下草鱼卵在被激活后 2 4min进入第一次卵裂前期 ,2 7— 30min处于中期 ,33min进入后期。由此可知被激活的草鱼卵子在第 2 4min时已经完成染色体的复制 ,使草鱼卵子雌核染色体人工加倍的最佳时期是在被激活后的 2 7— 30min这一时间区段内。此外 ,用不同热休克温度和不同的热休克强度处理已完成染色体复制的被激活草鱼卵 ,表明草鱼卵经 41℃处理 2min可得到较高比例的基因纯合型雌核发育二倍体鱼。
