The Sample Correlation
is computed
between trait data and any
other traits in the sample database selected above. Use
Spearman
Rank
when the sample size is small (<20) or when there are influential outliers.
Literature Correlation
The Literature Correlation
(Lit r) between
this gene and all other genes is computed
using the
Semantic Gene Organizer
and human, rat, and mouse data from PubMed.
Values are ranked by Lit r, but Sample r and Tissue r are also displayed. More on using Lit r
Tissue Correlation
The Tissue Correlation
(Tissue r)
estimates the similarity of expression of two genes
or transcripts across different cells, tissues, or organs
(glossary).
Tissue correlations
are generated by analyzing expression in multiple samples usually taken from single cases. Pearson and Spearman Rank correlations have been
computed for all pairs of genes using data from mouse samples.
