Computes the Log of the Coefficient of Variation Ratio between Factor A and the Control treatment.

Usage

lnCVR_ind(
  data,
  col_names = c("yi", "vi"),
  append = TRUE,
  Ctrl_mean,
  Ctrl_sd,
  Ctrl_n,
  A_mean,
  A_sd,
  A_n
)

Arguments

data

Data frame containing the variables used.

col_names

Vector of two strings to name the output columns for the effect size and it's sampling variance. Default is 'yi' and 'vi'.

append

Logical. Append the results to data. Default is TRUE

Ctrl_mean

Mean outcome from the Control treatment

Ctrl_sd

Standard deviation from the control treatment

Ctrl_n

Sample size from the control streatment

A_mean

Mean outcome from the treatment

A_sd

Standard deviation from the treatment

A_n

Sample size from the treatment

Details

See the package vignette for a detailed description of the formula.
