All,
I am new to the vcd package and new to R too.
1) I have a lickert analysis based data set.
2) I am doing a hypothesis tests on the variables ( like, is there a
relationship between the choice of a Doctor based on the Patients Income ,
that's just one example)
3) I am building contingency tables ( R x C) and running chiqsqr.test on
these tables.
These are mostly 2 x 2 tables. In some cases I am getting very low counts
of the variables in these ( R x C ) tables. I wanted to know at what point
do I need to use
chisqr.test with correction
fishers exact test
How do I show if there is any association between the variables in the R x
C setup?Should be I using oddratio() or or assocstats() or should I use
Cramers V test for 2 x 2 tables.
Please, advice or lead me to a source.
*Example of Case - Age of patients and If the Dr Justified a Diagnostic
Test on them.*
