我需要准备好天气数据集作为 keras 的输入。我在 3 年的每日数据中有 1096 个条目，其中第一个月缺失。我从附近的气象站得到了其中一个填写温度的列。但是，为了检查哪种插补最合适，我删除了这 30 个值，并将所有列保留为第一个月的 NA。然后，我尝试了各种估算包，包括 1. 小鼠 - 给出连续值但平均值太高；2. KNN (VIM) 给出的常数值太高 3.MissForest - 给出的常数值太高；4. imputeTS_interpolation - 给出的连续值略低；5. imputeTS_seasonal - 给定值略低。因此，我选择了 imputeTS_interpolation。并在用实际值填充温度列后使用它来估算剩余的列。然而，我似乎无法让 imputeTS 工作的季节性。知道为什么吗？请在下面找到使用的数据文件和代码： 代码：
# #MICE did not match with historical data too high avg of 10.2

# print(impute)
# xyplot(impute, Temp ~ Reco | .imp, pch = 20, cex =1.4)
# mf <- complete(impute, 3)
# mf <- cbind(mf, Date = df$Date.Time)
# write.csv(mf, "Mice_imputed.csv", row.names=TRUE)
