Re: Logistic regression analysis for two treatment groups and two time points?

Thanks for the advice. It gets more complicated than I expected.

Re: Detected or not detected as outcome for response variable - which type of logistic regression analysis?

Alright, thank you. Then, I will use binary logistic regression in this relatively simple case.

Detected or not detected as outcome for response variable - which type of logistic regression analysis?

Hi, If I have a response variable with detected or not detected (= factor below detection level or above detection level / present or not present) as the outcome, then which logistic regression analysis would I have to use: simple binary logistic regression or ordinal logistic regression? I mean, af...

Re: Logistic regression analysis for two treatment groups and two time points?

Thanks for the answer, reason180. I am bit confused now. Even though I don't want to compare treatment A and B regarding their effectiveness, I still want to find out the individual predictors for a response in case of treatment A or treatment B, and these may not be the same for the two treatments....

Re: Starting and connection problems with Jamovi when using firewall

Thanks again for the reply. I have been able to solve the problem now. In the software firewall I am using I can completely allow or disallow all connections for executable files. As mentioned in my previous posts, I allowed connections for the following files: C:\program files\jamovi 2.5.4.0\bin\ja...

Re: Starting and connection problems with Jamovi when using firewall

Thanks for the info. So far, I haven't been able to figure out why Jamovi still doesn't start when the firewall grants all the previously mentioned executable files full access (nothing is restricted). I started Jamovi in debug mode and when the firewall is enabled (while all Jamovil files should ac...

Re: Starting and connection problems with Jamovi when using firewall

I now added these files to the firewall for full internect access:
C:\Program Files\jamovi 2.5.4.0\Frameworks\python\python.exe
C:\Program Files\jamovi 2.5.4.0\Frameworks\python\pythonw.exe

Unfortunately, it still doesn't start with the firewall being active.

Starting and connection problems with Jamovi when using firewall

Hi, I have problems with Jamovi when using my firewall software under Windows. This firewall software normally asks for explicit internet access for all programs that need or want internet access. I can then allow or disallow it permanently or temporarily. I permanently allowed: C:\program files\jam...

Re: Logistic regression analysis for two treatment groups and two time points?

The research question is - more simply expressed: What predicts an effective response to the treatment at time point 1 and at time point 2, respectively?

Re: Logistic regression analysis for two treatment groups and two time points?

Alright, good to know. Would it be wrong to analyze the two different treatments as two independent experiments and hence perform two separate logistic regression analyses? Because what I want to know is which of the several potential predictor variables provide(s) a strong and statistically signifi...
