Thank you, this is good.🙏
I have a question, can you help me with a solution?
More grace, sir.
brother cor command is for correlation
Hi Emmanuel, Thanks for this video. If my data starts in 2nd or 3rd quarter, how do I specify that? Also, if I have 5 or 6 variables in my dataframe, how to make them all ts object?
If your data starts from the second quarter you can specify it using the start start. START = c(year, 2), frequency = 4
You can use the lapply function for more than one variable, data_ts<- lapply(your data[, 1:5], function(col), {ts(col, start=c(start year, quarter), frequency = quarter)})
Thank you professor
Thank you professor for excellent explanation
Glad i could help
100th Like! 😀
Hi Emmanuel, thanks for the informative video. I'm new in r and self-learning. I want to make time series graphs using ggplot2 and I have weekly data such as 2023-06-20, 2023-06-28 etc. I want to make a plot showing the date as it is with an interval of two weeks. Pls any guide, syntax or tips on how to go about it?
you need to format your data as a dataframe not a time series or 'ts' object.😀
wonderful video,can you make video on Garch model
Alright i will get on that ones am through with the project i have on ground.
I have daily data of three variables with some missing dates(data on some dates are not available so i remove theses dates),now what is the r code to make it time series,as first column is date column and other three are variable
what are basic temporal statistical summaries in time series?
Thank you I got it.
Glad i could be of help
I have watched Ur vedios,SPSS and R they are brief but with much information. Kudos.. I would like here from you on nested ANOVA
Alright then, you will get that soon

For Nigeria you can go to ng.investing.com/indices/nse-all-share-historical-data
This is well explained. Thank you Emma. Can you use scan()to read your data? what if you are trying to import the date using the Link for the data source? Finally, I would like to chat with you personally. Can you send me your Whatsapp number? Thank you.
Sure you can use it, but your data will be imported as vector after which you can convert the data to any form. x <- scan("stats.idre.ucla.edu/stat/data/scan.txt", what = list(age = 0, name = "")))
