Hello, I truly enjoyed watching the courses, but I wonder if I can have the data "indata",to excercise it well. Hope you get back to me as soon as possible.

hello sir. thanks for the tutorial. its super helpful. however, we could not get a full view of the code, as it is longer than the r studio display screen. can you provide the code please???

Weldone prof.

Thank you very much, this was very useful! best regards

Brother just write the exact codes for estimating Te,ae,ee and no additional symbol please. Finally do explain them as well. Anyways great video, you earned a new sub. Thanks dude!

please send me the the link program sfa stochastic analysis

This is so helpful ❤

Thank you sir

👏

what is the Stata comand to estimate AE

Dear Sir, Thanks for this detailed explanation on how to run sfa on R. I used similar steps from your session to estimate the labour use efficiency in an agro system. The results I got were not very convincing as all the variables were either not significant with very low P-values, a very high mean efficiency value of 0.90, and a gamma value of 0.99. I am a little skeptical about the results since they are not in line with what was expected. Could you guide me on what possible steps I could take or an explanation on what could be the issue? Thanks in advance

Joshua you legend you may have just saved my coursework.

Can you explain how to use the ppml estimator in R??

14:26 that plot of the filled and complete time series and the original time series with it's missing values looks like a really useful feature!😀

Sir, can you help with the interpretation of the analysis? I got lost in between the video please

Hello sir, 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?

Thanks a lot

Professor! Thank you very much ! if you have time, i hope to you upload about how run gravity model(ppml) in R!

Thanks prof for making this helpful video. We would appreciate it if you add another video using ARDL approach. Thank you

Wish you'd made all your code visible. Difficult to understand how you've defined the variables for the diagnostic plots

Thank you for the video. It came at the right time for my proposal project

Hi Mr. Joshua, would please help me with this problem,,, I used your code and I got this message Error: unexpected symbol in "casedat <- zoo(death$Outcome, seq(from = as.Date("2020/04/19"), to= as.Date("2021/02/28") by"

Very informative talk, thank you

Can you share sfa script text sir?

Error in as.date("1/1/1986") : could not find function "as.date" how can i fix this problem

sir, what code did you use to transfer your results to excel

thank you very much

Can we do this for air quality index dataset which contains aqi, nowcast and raw concentration

Excellent tutorial Joshua

You have to share the data so that we can apply

thank you for creating this video, sir

I am most grateful. Actually, God-sent. Firstly, your pedagogical style is superior! Would like to see more of your videos, especially in text analytics if you do any. I am having trouble in piping 1 by 1 unstructured datasets in order to proceed with data manipulation. I use tidytverse , dplyr, packages but get stuck right at the beginning after loading the data.

Thanks for the tutorial Prof, but where can I get the dataset you used?

hi can this plotting guide used for time series data? Currently i am doing ARIMA model for covid-19 data.

Dear sir. The sfa command is not working as it shown to me that number of parameters more than the number of observations. in such case, what can i do?

sir i want to say thank you very very very much, you literally saved my future, i am writing right now my bachelorhesis and your video helps me a lot, god bless you sir

Sir, you made the content too complicated.

Many thanks for creating this video! Very helpful!

Thank you for the video! Sharing the r script and the data would be great.

Can you please share the R script file on this UA-cam page? Thanks in anticipation.

Professor, thanks for your channel and the wonderful tutorials. Please how do you first set the data as time series data where R recognises the time variables in the data? What R commands do you use? I have monthly data in excel and CSV but when I import into R the time variable changes in some other numbers. How do I convert to time variable. Thank you.

U have done good Job sir

Very nice video, but please i know how to change the colors of the line if we don't like the auto created colors in the last example of autoplot of inflation and unemloyment. i will be waiting for your reply or simply send me the codes at starsami2015@gmail.com. thank you very much dear sir

How would I add an indicator to my list of countries

Sir, thank you for such a detailed analysis of the DEA

Thank you sir. Can you please make the data available so we can also practice with it?

when using VAR of vars package, even after completing values with methodes shown on 7:57, you always get error message of existing NAs

Hi Joshua. Thanks for the amazing video. I am getting an error when I am trying to use the sfa function in R. The system says "could not find function "sfa". I have followed the video step by step and will appreciate your help to overcome this issue. Thanks in Advance

Sir, good evening from India. I have 23 DMUs which 20 having efficiency value has one . I want to rank these based on sales and profit., how should I proceed?
