Signal-to-noise statistic
- Signal-to-noise statistic
In mathematics the signal-to-noise statistic distance between two vectors "a" and "b" with mean values and and standard deviation and respectively is:
:
This distance is frequently used to identify vectors that have significant difference. One usage is in bioinformatics to locate genes that are differential expressed on microarray experiments [Pomeroy, S.L. et al [http://www.broad.mit.edu/mpr/CNS/ Gene Expression-Based Classification and Outcome Prediction of Central Nervous System Embryonal Tumors] . Nature 415, 436–442.] .
