Malnutrition data (malnutrition data from UN)

来自联合国儿童基金会数据仓库的营养不良数据包括 1985 年至 2019 年在 77 个国家收集的两个变量，即发育迟缓和低出生体重患病率。发育迟缓定义为 0 至 59 岁的新生儿比例年龄别身高测量值较低的月份（低于两个标准偏差）。发育迟缓的数据代表一个点稀疏案例，每个国家有 4-23 个记录。低出生体重数据是部分稀疏案例，仅在 2000-2015 年期间记录。可用于泛函数据分析和稀疏泛函数据拟合。Malnutrition data from the UNICEF Data Warehouse contains two variables collected across 77 countries between 1985 and 2019: stunting and prevalence of low birth weight. Stunting is defined as the proportion of children aged 0 to 59 months with height-for-age z-scores below two standard deviations. The stunting dataset is a sparsely sampled functional case, with 4 to 23 records per country. The low birth weight dataset is a partially sparse case, with valid records only available during the 2000–2015 period. This dataset can be applied to functional data analysis and sparse functional data fitting.
