Formula for spearman correlation

Post by Hanna 12345 »

What formula does Jamovi 2.4.5.0. use for Spearmans rho? Is there a correction for tied ranks?

jamovi uses the cor.test(..., method='spearman') from R to calculate spearman's rho.

if you go noodling through the docs from R, you should be able to find what you need.

Hi

seolmatrix module uses the following R package to compute spearman cor.

# compute spearman correlation with psych package--------

spear <- psych::corr.test(mydata, method="spearman")

Best
