detectionPfixedNorm {sesame} | R Documentation |
The function takes a SigSet
as input, computes detection p-value
using negative control probes parametrized in a normal distribution and
returns a new SigSet
with an updated pval slot.

muG |

sdG |
SD of background in Grn channel |
muR |
mean of background in Red channel |
sdR |
SD of background in Red channel |
Background of Grn and Red are estimated separately from a fixed normal distribution. p-value is taken from the minimum of the p-value of the two alleles (color depends on probe design).
