ssdMeta: Sample size determination for replication success based on meta-analytic significance

Description

This function computes the standard error required to achieve replication success with a certain probability and based on statistical significance of the fixed-effects meta-analytic effect estimate obtained from combining original and replication effect estimates.

Usage

ssdMeta(level, dprior, power, searchInt = c(0, 10))

Value

Returns an object of class "ssdRS". See ssd for details.

Arguments

level

Significance level for the replication effect estimate (one-sided and in the same direction as the original effect estimate)

dprior

Design prior object

power

Desired probability of replication success

searchInt

Interval for numerical search over replication standard errors
