ri.r: Correlation replication interval

In replicationInterval: Replication Interval Functions

Description

Correlation replication interval

Usage

ri.r(r, n, rep.n = NA, prob.level = 0.95)

Arguments

r	Original study: Correlation
n	Original study: Sample size
rep.n	(optional) Replication study: Sample size. If not specified, n is used.
prob.level	(optional 0 to 1 value) Probability level desired (0 to 1). If not specified .95 (i.e., 95 percent) will be used.

Value

The replication interval and related statistics in list format.

Examples

ri.r(r=.35,n=100,rep.n=200)

Example output

Original study: r = 0.35, N = 100, 95% CI[0.16, 0.51]
Replication study: N = 200
Replication interval: 95% RI[0.13,0.56].


Interpretation:
The original correlation is 0.35 - with a replication interval 95% RI[0.13, 0.56] based a replication sample size of N = 200. If the replication correlation differs from the original correlation only due to sampling error, there is a 95% chance the replication result will fall in this interval. If the replication correlation falls outside of this range, factors beyond sampling error are likely also responsible for the difference.
