  1. Use of factor analysis to consolidate multiple outcome measures in chronic obstructive pulmonary disease.

    Article - En anglais

    Each patient had measurements made of 28 variables, including multiple parameters of pulmonary function, exercice tolerance and gas exchange.

    Factor analysis using a maximum likelihood iterative solution was performed.

    The factors were then rotated to a varimax solution.

    The analysis yielded four meaningful factors: exercise tolerance, disease severity, lung volumes and flow rates.

    Exercise tolerance and disease severity were the most important factors accounting, respectively, for 44 and 13% of the common variance.
