Examination scores of 16-year olds in Fife, Scotland.

Description

A dataset of examination scores of 16-year olds in Fife, Scotland, in which the secondary school the pupil attended is cross-classified by the primary school the pupil attended.

Usage

xc

Format

A data frame with 3435 observations on the following 11 variables:

vrq: A verbal reasoning score resulting from tests pupils took when they entered secondary school.
attain: Attainment score of pupils at age sixteen.
pid: Primary school identifying code.
sex: Pupils' gender: a factor with levels Male and Female.
sc: Pupils' social class (scaled from low to high).
sid: Secondary school identifying code.
fed: Fathers' education.
choice: Choice number of secondary school attended (where 1 is first choice, etc.)
med: Mothers' education.
cons: A column of ones. If included as an explanatory variable in a regression model (e.g. in MLwiN), its coefficient is the intercept.
pupil: Pupil identifying code.

Details

The xc dataset is one of the sample datasets provided with the multilevel-modelling software package MLwiN (Rasbash et al., 2009), analysed by Paterson (1991). The data are cross-classified in that not all children who attended the same primary school subsequently entered the same secondary school. See also Rasbash et al. (2012).
