Sir, thank you so much. I did not expect to find a video that could help me this much, I am currently working on a project of such analyze and this video really helped me.
Thank you so much sir. The explanation was very clear and understandable. I do not belong from coding background but could do it easily through your video. It helped a lot. Once again a big thank you.
Thank you very much, sir. The explanation and details were very clear and helpful. Do you have an application example on ARIMAX using R? I am dealing with R as a beginner. Once again thank you very much.
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?
Thank you for this video, i got the same values when i tried to forecast for the dataset i am working on, how do i resolve this please as it shouldn't be the same. thanks
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!

Good day, I tried qtr timeseries 2006 onwards. However if i give 2006.1 2006.2, 2006.3,.......... 2002.3 then I am getting an error msg. Hence, I gave 3,6,9,......,81 and got the forecast with frequency of 4. However I know it is wrong.. how to get around this problem
I've tried and I gt arima (0 0 0) does it means that it is nt suitable to forecast in arima method as I have small sample data? For small sample data what's other method are suitable?
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.

Excellent Explanation! But I have a question, sir. I have no trouble in executing acf(dataname) but if I do this 👉 acf(log(dataname)) it says"Error in plot.window(...):need finite 'ylim'values" Can you please help me with this? Thank you, in advance.
when i use the auto arima function in my data, the adq value given "000". and when i forecast by this adq value(000) the next all years forecasting data given same. why the adq value given "000"?? and why the all future forecusting value is given same???
Sir, I did the same steps as you did. But my dataset is at an interval of 5 years from 1975 to 2020, if I put h=2, it forecast the value for next 2 year for 2021 and 2022. I want the value at interval of 5 year. What should I do? Please suggest.

Hi Sir, may I ask is it applicable for small sample size of data, for example I have only 10 yearly data, can I use this method to forecast?
I've tried and I gt arima (0 0 0) does it means that it is nt suitable to forecast in arima method as I have small sample data? For small sample data what's other method are suitable?
You can use moving average forecast or exponential forecast method
I have a ques that when will use attach() function
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
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.
how do it works with the date, like 21/03/2024?
