Usage
convert.d.to.nnc(d, cer, r = 1,
eventDesirable = TRUE,
eventIfHigher = TRUE)

eventDesirable = TRUE,
eventIfHigher = TRUE)
Arguments
- d
- The value of Cohen's d.
- cer
- The Control Event Rate.
- r
- The correlation between the determinant and behavior (for mediated Numbers Needed for Change).
- eventDesirable
- Whether an event is desirable or undesirable.
