Hello,
I am interested in performing a Spearman's Correlation using QlikView.
Is there an extension for this? Do I need R for this?
Would someone please provide me a list of all the tests that QlikView can perform?
Thank you.
Michael
Theoretically any test that can be coded in vbscript or javascript can be performed. In practice you're probably better off doing any advanced statistical analysis in R.
Qlikview does have a correl function. Perhaps that suits your needs.
Look up the Statistical distribution functions and Statistical test functions in.... sections in the help file.
Hello,
either $ (id) identifying data
$ (f1) and $ (f2) the two data to compare
the respective ranks are given by:
aggr (num (rank (- $ (f1), 2)), $ (id)) ditto with $ (f2)
the correlation coefficient of spearman is then:
Correl (aggr (num (rank (- $ (f1), 2)), $ (id)), aggr (num (rank (- $ (f2), 2)), $ (id)))
Regards,

Bonjour,
soit $(id) identifiant des données
$(f1) et $(f2) les deux données à comparer
les rangs respectifs sont donnés par :
aggr(num(rank( - $(f1),2)),$(id)) idem avec $(f2)
le coef de corrélation de spearman est alors :
Correl(aggr(num(rank( - $(f1),2)),$(id)),aggr(num(rank( - $(f2),2)),$(id)))
regards,
