HoltWinters错误..。未用参数(h =

Question

数据：

data <- c(13,15,13,15,18,44,22,20,35,25,22,26,24,
          26,38,25,32,47,17,23,49,19,22,44,14,18,37)
ts <- ts(data, frequency = 12, start = c(2013,1))

我想提前12个月预测HoltWinters

tsHolt <- HoltWinters(ts, seasonal = "additive")
tsHoltPredict <- HoltWinters(tsHolt, seasonal = "additive", h = 12)
plot(tsHoltPredict)

但我得到了：

HoltWinters中的错误(tsHolt，季节性=“加性”，h= 12)：未使用的参数(h = 12)

Answer 1

predict()是你要找的吗？

tsHoltPredict <- predict(tsHolt, n.ahead = 12, prediction.interval = TRUE)

Answer 2

重新阅读library(forecast)文档似乎是：

forecast(tsHolt, 12)

也很管用！
