In arcaldwell49/SimplyAgree: Flexible and Robust Agreement and Reliability Analyses

Agreement Coefficents

Description

agree_coef produces inter-rater reliability or "agreement coefficients" as described by Gwet.

Usage

agree_coef(
  wide = TRUE,
  col.names = NULL,
  measure,
  item,
  id,
  data,
  weighted = FALSE,
  conf.level = 0.95
)

Arguments

wide	Logical value (TRUE or FALSE) indicating if data is in a "wide" format. Default is TRUE.
col.names	If wide is equal to TRUE then col.names is a list of the column names containing the measurements for reliability analysis.
measure	Name of column containing the measurement of interest.
item	Name of column containing the items. If this is an inter-rater reliability study then this would indicate the rater (e.g., rater1, rater2, rater3, etc).
id	Column with subject identifier.
data	Data frame with all data.
weighted	Logical value (TRUE or FALSE) indicating whether to weight the responses. If TRUE (default is FALSE) then quadratic weights are utilized. This option should be set to TRUE for ordinal or continuous responses.
conf.level	the confidence level required. Default is 95%.

Value

Returns single data frame of inter-rater reliability coefficients.
