Question

即使在AMELIA中应用边界，我也无法获得正面输入，我的结果中有一些负数并有警告：

警告讯息：
1：在min（x）中：min没有非缺失参数;返回Inf
2：在max（x）中：max没有非缺失参数;返回-Inf

我的代码是：

library(Amelia)

data <- read.table(file='Test.csv', sep=',', header=T, row.names=1)

x <- 30106
y <- 1

bds <- matrix(c(3, y, x), nrow = 1, ncol = 3)

a.out.bsd <- amelia(data, bound = bds, max.resample = 10, ords=c("distance_to_center", "stars", "city_id"))

out <- range(a.out.bsd$imputations$imp1[is.na(data[, 3]), 3])

write.amelia(obj=a.out.bsd, file.stem="Trivago", format="csv")

Answer 1

我找到了答案，当你没有放任何索引号列时会发生这种情况，似乎Amelia需要这个来应用边界。

hotel_id    city_id clicks  stars   distance_to_center
