Description

Compute Precision Analyses for Standardized Mean Differences

Usage

1
d_prec(d, nlow, nhigh, propn1 = 0.5, ci = 0.95, tails = 2, by = 1)

Arguments

d

Standardized means difference between groups

nlow

starting sample size

nhigh

ending sample size

propn1

Proportion in First Group

ci

Type of Confidence Interval (e.g., .95)

tails

number of tails for test (default is 2)

by

Incremental increase in sample (e.g. nlow = 10, nhigh = 24, by = 2, produces estimates of 10, 12, and 14)

Value

Precision Analyses for Standardized Mean Differences

Examples

1
d_prec(d=.4,nlow=100, nhigh=2000, propn1=.5, ci=.95, by=100)
