Hello,
I may have not dig enough but I don't find the answer in the community.
We have NGS like data, expression of genes, that we would like to correlates between different sample zones. The data are not normally distributed.
We have various inputs saying that we should use log transformation to get a normal distribution.
We want to study tha correlation, can we do it on non-normal distributed data? Do we need to go for the log distribution?
The correlation are not the same using one or the other method so we want to be sure we are doing it the right way are we are not statisticians.
Thanks to anyone that can help us on that point.
Have nice day
Marie
