Sir my forecasting point is same value

Nice, thank you for the video. However why you didn't do Training and Testing?

How can i talk to you

Hello may i talk you

Thank you professor

Amazing video, thank you for the explanation, sir.

Hi insightful video but you have interpreted the Box Ljung test incorrectly!

Awesome! For the first time, best guidance i have got. The lecture is informative. Great thanks!

hello sir, I have one doubt u not did any differerence but auto.arima gives d as 2 why its like this?

Last week I called Joseph and he said that “Don not go Monte Carlo. Because I lost everything in gamble! Gamble is Sin!” In my opinion, do not use this method!

how do it works with the date, like 21/03/2024?

the best explanation i found out after browsing through so many other videos

Very useful video sir. Sir if possible please upload videos for confirmatory factor analysis.

Thanks

one of the best videos i have ever seen about R. sir great job...not the best job

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?

Thankyou for the video, Sir. But you have used 0.05 and 0.5 interchangeably multiple times. especially while you were explaining communalities. Please check that as it is very confusing for those learning from this video

thanks sir what about communalities for minimum data set

@ SimpleSPSS: How can we apply this model to multiple columns. Please help regarding this

thank you so much, wanted to inquire about how to test the model by using the model to show some current values in the table

very helpful, thank you so much. very clear much appreciated sir.

yeah sir, you are going in very smooth way. Thank you very much. #Respect

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

Can I get codes for doing hierarchical clustering using wards method at R studio

What's the code for formulating the model of arima with drift Include.drift=true is not working. Is there any pre package we have to install to perform drift code

What communalities Indicate? What is the meaning?

thank you soo much friend its really helped me and you explain it very efficiently. thank you sir

This helped a lot thank you

I have a ques that when will use attach() function

Thank you very much sir, it has been helpful to carry out my project using your tutorial may God bless you,am Yusuf haji from Kenya

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.

How do you report on the coefficients? Thanks

Could you please share the xlsx file? Your teaching is very intuitive. I want to replicate what you did and learn. Thank you.

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.

My Rstudio shoes error in getting the forecast and tseries package what do i do

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

How to do time series analysis on categorical data?

s/o to the homie ! helped me a lot

what do you mean by autocorrelation should not be there? There is no condition for stationary data must have no autocorrelation, where did you read it?

Sir please what are the necessary packages to be installed

Adf test is not installed I’ve tried many options it’s just not working for the dataset it’s a yearly data set

Dear Sir, how to do winter's additive or mulltiplicative model?

Sir Is there any video for multivariate time series in R

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.

My point forecast are coming as constant values.

Thank you very much. This video saves my life😂. But I wonder Arima is for short-term forecasting?

Hello Sir, I find this error while following your video" Error in as.ts(x) : argument "y" is missing, with no default", can you please help me with that. Thank You

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?

15:58 You dont need ts() in acf, pacf : enter directly acf(gdpmodel$residuals) ...
