convert.d.to.nnc: Helper functions for Numbers Needed for Change

In Matherion/ufs: Quantitative Analysis Made Accessible

Description

These two functions are used by behaviorchange::nnc() to compute the Numbers Needed for Change.

Usage

convert.d.to.nnc(d, cer, r = 1, 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.
eventIfHigher	Whether scores above or below the threshold are considered 'an event'.

Value

The converted value.
