Computing the James-Stein Shrinkage Entropy Estimate of cellCounts
.
1 | entropyShrink(cellCounts, unit = unit, shrinkageTarget = shrinkageTarget)
|
cellCounts |
an integer vector (or matrix) representing the number of times each particular count is obtained. |
unit |
the unit in which entropy is measured. One of |
shrinkageTarget |
shrinkage target frequencies. If not specified (default) it is estimated in a James-Stein-type fashion (uniform distribution). |
The entropyShrink
function returns the value of the entropy of that gene
H(X)
(or pair of genes H(X,Y)
).
