I want to forecast the hourly rate of electricity using ARIMA. But, I won't be able to set the ts function correctly which results in no forecasting in Arima. My data has 24 entries per day. My aim is to predict 2022-05-01 18:00:00
Please help.
Here is code: start date: 07/01/2015 1:00, end date: 4/26/2022 15:00
data$Category <- as.Date(data$Category, format = "%m/%d/%Y")
data <- data[order(data$Category), ]
Y <- ts(data[,2], start = c(2015,07,01), frequency = 365*23)
fit_arima <- auto.arima(Y, d=1, D=1, stepwise = FALSE, approximation = FALSE, trace = TRUE)
print(summary(fit_arima))
checkresiduals(fit_arima)
