HoltWinters 错误 ... 未使用的参数（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))

我想用 HoltWinters 预测未来 12 个月

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

但我得到：

Error in HoltWinters(tsHolt, seasonal = "additive", h = 12) : unused argument (h = 12)

Answer 1

predict()是您要找的吗？

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)

同样有效！
