Hello! What is the error message, please? At first glance, you are using the "ts" function. That doesn't work for hourly frequency. You may want to create a zoo object. This is Round One.

Hi, I would like to ask a question about time series. I am trying to convert my data into time series data. I have hourly data from ?2015-12-18 00:00? to ?2017-10-24 23:00? I am trying the following codes but they are not working. Could you help me out? tseri <- ts(data ,seq(from=as.POSIXct("2015-12-18 00:00:00"), to=as.POSIXct("2017-10-24 23:00:00"), by="hour"))

...it gave me the true value. Do you think it is okay? By the way, I appreciate for fast reply.

Hi, I am would like to ask few questions. I am trying to forecast hourly electricity prices by 24 hours ahead. I have hourly data starting from 2015*12*18 to 2017-10-24 and I have defined the data as time series as written in the code below. Then I am trying do neural network with 23 non-seasonal dummies and 1 seasonal dummy. But I don?t know whether training set is enough.( Guess it is 50
