Dear Prof, Thank you so much. I am working on the ARIMA model for the forecast and following what you have said. Series qualified as stationary. The Sigma^2 is too large for my model like 1.107e+10. My data has too many zeros and the forecasts show the same values for the next ten years. Can I still use this ARIMA model to forecast?

Sir, I like your video; it is the easiest to follow that I have come across. Unfortunately, I am still struggling with R and getting the data frame to convert to a ts object. I have 3 years of daily data which was thinking of showing as monthly. Should I recalculate my raw data and pre-convert this to monthly. What would the coding be to convert this data-frame? Thanks.

Hello there, I had something similar. Here is my code require(tidyverse) data % group_by(week = format(TRANSACTION_DATE, '%Y-%U')) %>% summarise_if(is.numeric, sum) And then split the colum into a year and a separate week: data_splitted % separate(week, c('YEAR', "WEEK")) then I grouped each dataobject per year: Data2018 % filter(data_splitted$YEAR == 2018)

Thank you, great video! When I run an ARIMA forecast or plot the residuals, the x-axis always changes to period (e.g. 1, 2, ... 3000) in days, instead of being in dates or years. Any idea how to change this? Lots of conflicting info online but nothing seems to work...Thank you!

@asraarahmed4765
@asraarahmed4765 Год назад
Attach will help r software to read the dataset columns readily. That is you need not use long code like $ sign to select each time
@asraarahmed4765
@asraarahmed4765 Год назад
Attach function will help R to read all the column names present in the dataset. No need to write dataset name and column /Variable name again and again in code.
