Hi! You can always import an excel sheet into R using read_excel() in the readxl package, for instance. I'll be putting out more videos on different aspects of data analysis all year long.
Sir, can you please make a video that how to predict demand quantity using arima model in r, I have learn how to forcast using arima model but lastly I cannot found final prediction data in my main data. So atlest can you give me idea how I can add my prediction data in my dataset
so, how can one build a confidence interval with an x value that is not in the dataframe? I am only getting the interval for my values in the dataframe. my code is predict(My_Linmod,data.frame(X=c(2,4)),interval="confidence",level=0.99). I don't have 4 in my dataframe and my linear model is Y^=10.2+4*X so I know Y^ is 26.2. I can't build a 99% C.I for X=4, but it shows for X=2 since 2 is in my data.
Hi! This should work, so you'll need to recheck your model. For another example of the predict() function, take a look at this vid on multiple regression: ruclips.net/video/2Pp6Bd5kb08/видео.html

this is honestly the best video explaining regressions to the most laymen person. thank you
Yay! So glad it's helpful!
thank you king you saved my life with this
This is a very good video and helped me a lot. Thank you
the smile at the end :D
Very good for quick undestanding!
Thank you so much for sharing this tutorial.
I'm so glad it was helpful!
The video sound is pretty good, beyond my imagination
Very helpful video, thank you!
Great tutorial! Subscribed
Yay! Thank you!
Thank you, concise and clear!
great tutorial. Can you also kindly explain the Dirichlet regression model and how to interpret the summary output?
Great suggestion! It’s on my to-do list.
Great tutorial!
Thanks!
Thanks so much!
I'm glad it helped!
very helpful, thank u
thx !
Thank you!
thanks g
Thanks for d video. It was very helpful. I have a question pls… How can i put my predicted values in a tabular form pls?
Hi! Check out the broom package here: ruclips.net/video/Oy1_A_ZhCY0/видео.html. You'll love it!
Sir could you make a video on how can we do data analysis on collected data which you have recorded in an excel sheet.

Great suggestion, thanks! I'll put ARIMA on my to-do list.

6:24 data.frame()
How can i do a polynomial regression using the function "lm" ?
Hi! This simplest thing is to add higher-power terms to your model, like y ~ x + I(x^2), for instance. I promise a vid on this eventually.
