signal.normexp {limma} | R Documentation |
Adjust foreground intensities for observed background using Normal+Exp Model.
This function is called by backgroundCorrect
and is not normally called directly by the user.
signal.normexp(mu,sigma,alpha,foreground)
mu |
numeric vector giving expected values for signal |
sigma |
numeric scalar giving standard deviation of background intensities |
alpha |
numeric scaler giving exponential decay rate of foreground intensities |
foreground |
numeric vector of foreground intensities |
In general the vector mu
is computed conditional on background at each spot.
Numeric vector containing adjusted intensities.
