phis {mmgmos} | R Documentation |
The pre-estimated parameters of log normal distribution of phi, which is the fraction of specific signal binding to mismatch probe.
data(phis)
The format is: num [1:3] 0.171 -1.341 0.653
The current values of phis are estimated from Affymetrix spike-in data sets.
It was loaded in the method "mmgmos"
.
phis[1:3] is respectively the mode, mean and variance of the log normal distribution of phi, and phis[1] is also the intial value of phi in the model optimisation.
