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错误(tsHolt,seasonal =“additive”,h = 12): 未使用的参数(h = 12)
答案 0 :(得分:2)
predict()
您要找的是什么?
tsHoltPredict <- predict(tsHolt, n.ahead = 12, prediction.interval = TRUE)
答案 1 :(得分:0)
重新阅读library(forecast)
文档似乎:
forecast(tsHolt, 12)
也有效!
