In iotarelr: Iota Inter Coder Reliability for Content Analysis

Get Iota2 Measures

Description

Function for calculating the elements of the Iota Concept 2

Usage

get_iota2_measures(aem, categorical_sizes, categorical_levels)

Arguments

aem	Assignment Error Matrix.
categorical_sizes	Probabilities for the different categories to occur.
categorical_levels	Vector containing all possible categories of the content analysis.

Value

Returns a list of all measures belonging to the Iota Concept of the second generation. The first component estimates_categorical_level comprises all elements that describe the ratings on a categorical level. The elements are sub-divided into raw estimates and chance-corrected estimates.

raw_estimates

iota:

A vector containing the Iota values for each category.

iota_error_1:

A vector containing the Iota Error Type I values for each category.

iota_error_2:

A vector containing the Iota Error Type II values for each category.

alpha_reliability:

A vector containing the Alpha Reliabilities for each category. These values represent probabilities.

beta_reliability:

A vector containing the Beta Reliabilities for each category. These values represent probabilities.

assignment_error_matrix:

Assignment Error Matrix containing the conditional probabilities for assigning a unit of category i to categories 1 to n.

elements_chance_corrected

alpha_reliability:

A vector containing the chance-corrected Alpha Reliabilities for each category.

beta_reliability:

A vector containing the chance-corrected Beta Reliabilities for each category.

The second component estimates_scale_level contains elements for describing the quality of the ratings on a scale level. It comprises the following elements:

iota_index:

The Iota Index, representing the reliability on a scale level.

iota_index_d4:

The Static Iota Index, which is a transformation of the original Iota Index, in order to consider the uncertainty of estimation.

iota_index_dyn2:

The Dynamic Iota Index, which is a transformation of the original Iota Index, in order to consider the uncertainty of estimation.
