Compute Precision Analyses for Standardized Mean Differences
d_prec(d, nlow, nhigh, propn1 = 0.5, ci = 0.95, tails = 2, by = 1)
Standardized means difference between groups
starting sample size
ending sample size
Proportion in First Group
Type of Confidence Interval (e.g., .95)
number of tails for test (default is 2)
Incremental increase in sample (e.g. nlow = 10, nhigh = 24, by = 2, produces estimates of 10, 12, and 14)
