Function for estimating the Average Power Rate (APR), also called Sensitivity. Similar to the FDR estimator of Storey and Tibshirani (2003).

1 2	estimateAPR(alpha, p_values, p_values_adjusted, lambda = 0.5)

`alpha`	the type I error level
`p_values`	the raw p-values from the tests at level alpha
`p_values_adjusted`	the p-values adjusted for multiple testing
`lambda`	a tuning parameter. Default value 0.5 as suggested by Storey and Tibshirany (2003)

The estimated APR, which is a single value in [0,1]

estimateFDR

## generate some p-values
p_values <- runif(100)
p_values_adjusted <- p.adjust(p_values, method="BH")

## estimate the power
## Not run: estimateAPR(alpha=0.05, p_values=p_values, p_values_adjusted=p_values_adjusted)
