Fit models for calculating meta-regression in R Studio

Navigation
1

I started using R Studio a short time ago to do a meta-regression analysis using the mada package. I need to create a fit template for each variable and after creating 6 templates the R started to give an error saying that it is not finding the object. Someone how to help me? Is there a limit of fit values that can be created? Thank you

Considering that you ran this in R 

> madad(cbct.pr.sa) 
> summary(fit.cbct.pr.sa.Metodo) 
> summary(cbct.pr.sa$Metodo) 
> fit.cbct.pr.sa.Metodo <- reitsma(cbct.pr.sa, + formula = cbind(tsens, tfpr) ~ Metodo)

Your code seems to have several problems:

  • In the first line you do not assign the result of the function to any object. So, then the summary will not work.

  • The order of execution seems strange, you ask for summary of an object that is created later.

    • See if that works: 

    summary(cbct.pr.sa$Metodo) 
fit.cbct.pr.sa.Metodo <- reitsma(cbct.pr.sa, formula = cbind(tsens, tfpr) ~ Metodo) 
summary(fit.cbct.pr.sa.Metodo)

    I was unable to identify the purpose of madad(cbct.pr.sa) in your code. There is no limit of fits that can be created.
