tmixture {limma} | R Documentation |
This function estimates the unscaled standard deviation of the log fold change for differentially expressed genes.
It is called by the function ebayes
and is not intended to be called by users.
tmixture.vector(tstat,stdev.unscaled,df,proportion,c0lim=NULL) tmixture.matrix(tstat,stdev.unscaled,df,proportion,c0lim=NULL)
tstat |
numeric vector or matrix of t-statistics |
stdev.unscaled |
numeric matrix conformal with tstatf containing the unscaled standard deviations for the coefficient estimators |
df |
numeric vector giving the degrees of freedom associated with tstat |
proportion |
assumed proportion of genes which are differentially expressed |
c0lim |
optional upper limit for the estimated unscaled standard deviation |
Numeric vector of length equal to the number of columns of tstat
and stdev.unscaled
.
