由于“非遗漏观察次数太少”错误导致R中的ARIMA预测脚本出现问题,并且希望在自己对其进行故障排除失败后寻求一些帮助。
我的确切脚本非常简单,如下所示:
library(forecast)
SalesData <- aggregate(Revenue~SalesCategory+Month, data = dataset, FUN = sum)
SalesForecast <- ts(SalesData$Revenue, start = 0, freq = 12)
fit <- arima(log(SalesForecast), c(1, 1, 0),
seasonal = list(order = c(1, 1, 0),
period = 12))
pred <- predict(fit, n.ahead = 12)
Adjusted.pred <- (2.718^pred$pred)
ts.plot(SalesForecast,Adjusted.pred, log = "y", ylab= "Revenue",
lty = c(1,3),main = "Forecasted Revenue", xlab ="Fiscal Year Months")
值得注意的是,我的销售数据是季节性的,从2013年7月到2016年8月延伸。在此期间,某些产品已被弃用或新增。在重新确定优先级之前,还有一些产品被弃用了几个月,我认为这可能是问题的根本原因。
感谢关于可能是一个非常基本的问题的任何和所有帮助或指导。
最佳, 杰克
