Dear group and GSVA team, 

I am seeing enrichment score (es.obs) for gsva range from -0.9994342  0.9999434. 

> range(mresgsva)
[1] -0.9994342  0.9999434

why are ES.obs scores ranging from -1 to 1. Is this score similar to correlation coef ?

Any help is appreciated and thanks in advance. 

mresgsva <- gsva(mdat2, geneSetsall, mx.diff=FALSE, verbose=FALSE, parallel.sz=1)$es.obs

Adrian.
