university1992: Druzdzel and Glymour's University Data 1992

In SIN: A SINful Approach to Selection of Gaussian Graphical Markov Models

Description

Data from a study by the U.S. News and World Report magazine with the purpose of college ranking. Druzdzel and Glymour choose 8 variables and after removing some universities give a correlation matrix for 170 universities. The 8 variables are:

apgra

average percentage of graduation, i.e., the fraction of the total number of entering students who make it through the graduation,

rejr

rejection rate, i.e., the fraction of the applicants who are given an admission offer,

tstsc

average standardized test scores of the incoming students,

top10

class standing of the incoming freshman, which is a fraction of the incoming freshmen who were in top 10% of their high school graduating class,

pacc

percentage of those students who accept the university's offer from among those who are offered admission,

spend

total educational and general expenses per student, which is the sum spent on the instruction, student services, and academic support, including libraries and computing services,

strat

student-faculty ratio,

salar

average facutly salary.

Format

A list providing a summary of the data. The list contains:

university1992$means	:	the mean vector,
university1992$stddev	:	the vector of standard deviations,
university1992$corr	:	the correlation matrix, and
university1992$n	:	the sample size.
