Abstract:Software reliability and software complexity are closely related issues in software development. An elegant definition of relative complexity was proposed in [1,2]. The definition given in [1,2] needs modification. Depending on how many factor loadings are used in the factor analysis different complexity results are obtained. Hence the definition of relative complexity given in those papers is subjective. The object of this paper is to suggest a modified definition of relative complexity. Different measures based on the magnitude of the eigenvalues obtained from the correlation matrix are suggested in this paper. The relative complexity of 27 programs given in [3] has been calculated using different factor loadings.
