Proportion Overlap Calculations for Cohen's d

Description

This function calculates the proportion overlap from two independent group d effect size calculations. Cohen's u1, u2, u3 and proportion overlap are provided.

Usage

proportion_overlap(
  model = NULL,
  x_col = NULL,
  y_col = NULL,
  df = NULL,
  d = NULL
)

Arguments

model	a saved independent t-test model
x_col	name of the column that contains the factor levels OR a numeric vector of group 1 scores
y_col	name of the column that contains the dependent score OR a numeric vector of group 2 scores
df	optional dataframe that includes the x_col and y_col
d	previously calculated d value

Value

A list of the following:

u1	Proportion of non-overlap across both distributions
u2	Proportion that one group is more than the same proportion in the other group
u3	Proportion of one group that is smaller than the median of the other group
p_o	Proportional overlap of distributions

Examples

proportion_overlap(d = .25)
