Missing values

Mart-in

Hello,

 

I want to make analysis (Chi2 test) but I would make it without missing values.

 

I don't find the formule in order to doesn't take in account this missing values.

 

Moreover, I would make a Chi2 to compare the proportion with a EVA pain level ≥4 (cf. variable in yellow) according to the Intervention (salmon color) = 0 between the 2 randomization groups (variable in red).

 

You will also find my data base in file attach.

 

Thank you +++

 

Vocab : "Données manquantes" = missing values ; EVA < 4 (code = 1 for EVA variable (in yellow) ; EVA > 4 code = 1 for EVA variable (in yellow) ; "Bras prise en charge habituelle" --> cf. Bras randomisation (in red) ;

I may have misunderstood your question, but what I think you want is to

1.  ignore the missing values in the EVA column (I just selected those rows and hid and excluded them), and

2.  look at the Fit Y (yellow) by X (salmon) separately for the 2 randomization groups (red), which I did by putting the randomization groups in the By box.

Attached is the file, and I'm sorry if I did not understand you correctly.
