bstspost's Issues

It seems as.Date(time(AirPassengers)) Doesn't Work for Me

I got the error below using the code in the blog post.

The code below, however, creates date object by leveraging zoo package.

d1 <- data.frame(c(10^as.numeric(fitted(arima)), # fitted and predicted
                   10^as.numeric(predict(arima, n.ahead = 12)$pred)),
                 as.numeric(AirPassengers), #actual values
                 as.Date(as.yearmon(time(AirPassengers)))

Need Help

I am using a "10 years" monthly time-series data to run this code. But getting "Error in data.frame(c(10^as.numeric(-colMeans(bsts.model$one.step.prediction.errors[-(1:burn), :
arguments imply differing number of rows: 144, 120"

d2 <- data.frame(

# fitted values and predictions

c(10^as.numeric(-colMeans(bsts.model$one.step.prediction.errors[-(1:burn),])+y),  

10^as.numeric(p$mean)),

# actual data and dates 

as.numeric(AirPassengers),

as.Date(time(AirPassengers)))

names(d2) <- c("Fitted", "Actual", "Date")

Please help me to sort out this error.

Great post! Couple questions

looks like you are creating a variable called arima that is the same name as the function of arima. This is leading to an error getting thrown - object of type 'closure' is not subsettable

Not too big a problem, rename it arima.plane or something and that error goes away.

Next error that pops up for me is Error in data.frame(c(10^as.numeric(fitted(arima.plane)), 10^as.numeric(predict(arima.plane, : arguments imply differing number of rows: 156, 144

Maybe you will have time to update code at some point. Thanks!
