in which NA are missing values,i want to predict/forecast it,i search on internet,i found that Amelia packages can impute missing values; i used but it giving error,how can i resolve it library(Amelia) t<-read.table("C:\\Users\\exam\\Desktop\\missing_ts.txt") > a.out <- amelia(t) Amelia Error Code: 42 There is only 1 column of data. Cannot impute > amelia(x=as.matrix(1:101,t$V1)) Amelia Error Code: 39 Your data has no missing values. Make sure the code for missing data is set to the code for R, which is NA > amelia(t$V1) Error in colSums(!is.na(x)) : 'x' must be an array of at least two dimensions is my way of predicting wrong?,if yes,then which method should i follow? -- View this message in context: http://r.789695.n4.nabble.com/how-to-predict-forecast-missing-values-in-time-series-tp4630588.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
