calcallgroups {SSrat}

Calculates the social status determinations of multiple groups.

Description

Calculates the social status determinations from a SSrat compliant dataframe, as described in readratdatafixed.
The dataframe may contain multiple groups. This function can only be used when the rating scale is equal for all groups.
Basically, this function calls the calcgroup function as often as there are groups in the SSrat compliant dataframe.
The resulting dataframe with social sttaus determinations can be analyzed with standard tools for statistical analyis, such as linear regression (lm). Other data, such as background variables can be added to the dataframe.

Usage

calcallgroups(dataframe, alpha = c(0.1, 0.05, 0.01), NBcriteria = F)

Arguments

dataframe

The input dataframe with the rating data. This dataframe should have columns schoolid, groupid, respid, and for n raters n columns named "r01", "r02" .. "r<n>", with a maximum of r99.

alpha

The significance levels to be applied to the probability distributions of the four total scores that have been derived from the ratings. By choosing an appropriate alpha, the user can fine tune the criterion for the status determination. A list of various alphas can be supplied. Default is the list (.10, .05, .01).

NBcriteria

A boolean. When TRUE, the classification criteria of Newcomb & Bukowski (1983) will be applied, in stead of the SSrat criteria. These criteria are applicable to three-point rating scales. When this option is selected for longer scales, the scale midpoint is recoded to 2, all scores larger than the midscore are recoded to 3 and all scores lower than the midscore are recoded to 1. When another recoding scheme is preferred, the input ratings themselves should be recoded (use recode from package car).

Details

See function calcgroup for more details.

Value
