var_error_delta: Estimate the error variance of Glass' delta values

Description

Estimate the error variance of Glass' delta values

Usage

var_error_delta(delta, nc, ne = NA, use_pooled_sd = FALSE,
  correct_bias = TRUE)

Arguments

delta

Vector of Glass' delta values.

nc

Vector of control-group sample sizes (or the total sample size with the assumption that groups are of equal size, if no experimental-group sample size is supplied).

ne

Vector of experimental-group sample sizes.

use_pooled_sd

Logical vector determining whether the pooled standard deviation was used (TRUE) or not (FALSE). FALSE by default.

correct_bias

Logical argument that determines whether to correct error-variance estimates for small-sample bias in d values (TRUE) or not (FALSE).

Value

A vector of sampling-error variances.

Examples

# NOT RUN {
var_error_delta(delta = .3, nc = 30, ne = 30)
var_error_delta(delta = .3, nc = 60, ne = NA)
# }
