\textbf{Question 1}
\par\smallksip
The probability of having the virus can be given as 0,2\%. In the case a person has the virus, a test is certain positive with the probability of 90\%. In the case that a person does not have the virus the probability of a positive test is 5\%.
\par\smallksip
What is the probability that a positive tested person actually has thev virus?

How to represent sub-categories odds ratio by forest plot??
top Video
wie kurz und dennoch so stark erklärt wow 👏
Danke! Viel Erfolg
Please when i replace missing value by mean, it's doesn't have a changement on the interpretation of my data?
Certainly it does and it depends on the way you set up your data. I just showed how to do it and what you are going to do is up to do. Each data set ( hopefully at least each research) is unique
very very helpful video. I have one question. Can we do funnel plot with metan code using odds ratio and confidence interval? how?
I think it is explained in the other video
Thanks
Stats gives an error, "repeated time values within panel" Please tell me how to resolve this?
Danke habt mich gerettet gerne weiter so
Stata tells me that "command asdoc is unrecognized". How to fix it ? Thanks
Try ssc install asdoc first
@@mathexplain3149 It works, thank you !!
thank you very much for very helpful video, can you please explain how to add p-values for odd ratio in forestplots. thanks
Thank you a lot, Sir 😊😊😊
Nix gecheckt
Danke für das Video! Wenn ich nur die Verteilungsfunktion gegeben habe muss ich die vorher in die Dichtefunktion umrechnen oder? Oder kann ich den Erwartungswert auch direkt mit der Verteilungsfuntion berechnen?
gilt das wirklich für alle stetige Zufallsfunktionen oder gibt es da Ausnahmen?
Gilt für alle
Thank you for the video. Do you have a trick to display odds ratios on a log scale in the forest plot?
I think it might be an option in the command. Check the options

Hello I need your help with my data, could you please share your email or contact information? Thanks in advanced!
Hi, I am running a Hausman panel ARDL model in Stata. I have successfully run the pooled mean group (PMG) regression successfully. Now, I want to run the mean group (mg) regression then after getting the mg results, I will run the Hausman test to decide which is best. However, when running the mg, I get an error message as the maximum number of iterations exceeded, r(498). Could you help me with what to do?
you saved me
Gut Erklärt vielen Dank. Hab’s für meinen Informatik Studiengang gebraucht.
Weiterhin viel Erfolg 🤞
This was so quick. Thanks so much! I liked and subscribed to show my appreciation ❤️
Thanks mate!
Hi, Is it possible to format the text of the of the groups, in your case the countries? I would like to be able to put in bold the group (in your case Germany, USA, Japan). Do you know a way?
Yes, this possible. See options for more
Really useful! Thank you
So helpful. I have a problem my stata does not recognize command "mdesc"
try ssc install mdesc
@@mathexplain3149 Thank you this worked
i love you
Sehr gut erklärt hab es für die Uni gebraucht danke!

Genial wie immer. Danke
Top wie immer
Thank you so much for your helpful video . i doing meta analysis of prevalence studies and could share me a video how to conduct this metaproportion and i m need to do sensitivity analysis fo those studies and could you share a video. could you share us the commands in pdf or word format. thank you very much .
thank you
This is a life saver. Been searching the web a lot for an easier way to extract summary statistics tables as well as other tables like correlation tables. This works for all of them. Thank you. please post more STATA videos!
Thank you soo much sir it is very useful and it works me very well thank again
This is so life-changing! Thanks so much for this! I remember how hard it was to export the results into doc back in the day!
How you can treat them, in case we have a lot of missing values !! (more than 60% missed)?
the answer of your research question with this data Set may be discussed with caution
Perfekt
it does'nt work with me ! can you give me another method please :) !
cheers
Thanks sir, iI am doing meta analysis on the effect of external debt and economic growth using partial correlation approach. FE AND RE models. Hence could you give me helpful videos?
I really like your videos! You are explaining it precise with all the details! I would be happy to see more videos of you like explaing how to do a panel regression in stata
Thanks !

How to add more than two variables on one forest plot?
Hi! Thanks for the insightful video! I was wondering if you could perhaps share line 15 from the Do file from the video. I looked in the Do files in the Google drive link you shared but I could not find this line in there. Specifically, I would like to know what comes after the part: addnote(hi""de. Also, I have some trouble with the F test. When I copied line 15 from the Do file in the video, I got the error message: invalid ' "F test' r(198) Do you perhaps know what I did wrong? Thank you in advance!
hi please upload you Do-file ( Botswana_advanced), I want to see your line 15
great job
mdesc is not working in case of panel data.
same neither "list if missing"
It's working for panel data.
Thank you for this video! Is there a way to specify the varlist as a list of all variables without having to identify them one by one?
Wieso wendet man bei der Stammfunktion den Kehrwert an und was passiert wenn eine minus vor dem Bruch steht?
