This function calculates the success of gene screening.
corPredictionSuccess(corPrediction, corTestSet, topNumber = 100)a vector or a matrix of prediction statistics
correlation or other statistics on test set
a vector of the number of top genes to consider
difference of meancorTestSetPositive and
meancorTestSetNegative below
mean corTestSet on top genes with positive corPrediction
mean corTestSet on top genes with negative corPrediction
For each column in corPrediction, the function evaluates the mean corTestSet for the number
of top genes (ranked by the column in corPrediction) given in topNumber. The higher the mean
corTestSet (for positive corPrediction) or negative (for negative corPrediction), the
more successful the prediction.
