Where is the value for probe i on array j and is the mean value for control oligo c on array j Array Where is the value for probe i on array j and is the value for probe i on control array/channel c Explanation of the three normalized statistics offered by DetectiV. the results. Results were first filtered such that groups had a normalized log2 ratio greater than or equal to 1 (a ratio of two to the control) and then sorted by p value.
