What Code you are looking for? Is there any in all types of Metanalyses?

Wisam

Louai Alsaloumi

I need a code for Rstudio to perform the analysis and show the results (p value of the model, I^2..etc) in the graph.

I am sorry colleague really I didn't understand what you are asking about. I have done and evaluated more than 10 Metanalyses bit never used a code?

Maybe a statistician can help you better!?

Regards

Dear Louai

At last, I could understand you! You're requesting an activation code for RStudio which a new software! Yet on personal grounds I never advise you to use pirated software! They Will hack your computer and damage it!?

Indeed, it is true. Once I have set up a pirated software which belongs back in 2005?

They hacked my Modem!? And till today I can't use it! In addition, they removed the very characteristic which comes with my browser (slimjet) to download videos from YouTube! Till the present day!?

Accordingly, I advise you to download Mecalc which simple, highly user-friendly software, and buy it. Believe me, it will be easier for you to complete your research!

Good Luck

Apologies Louai Alsaloumi for creating another question within your question profile. I am new into the meta-analysis concept. Having done a little reading and watched videos on youtube I understand there are different kinds of meta-analysis. And the type of estimate also depends on the data, the field and the relationships that exists in theory.

I am from an engineering field. I am working on Lifecycle assessment (LCA) of wastewater treatment plants(WWTPs). I want to understand the reasons for variations and the extent of these variations in LCA studies. This looks like a problem that could be tackled with meta-analysis.

My little concept is ''Among WWTPs, compared using LCA, what are the effect of 2 factor such and technical and methods factors(each factor has about three levels) on the outcome (energy use, GWP, ATP etc.).

Dear Wisam Akram , Hongyang Ma ,Proloy Barua could you kindly suggest the type of Meta-analysis, estimates/ratios, random/fixed effect model, and reference material that could be of help. thank you
