# Journal on financial ratio analysis

Foulke, R. However, applications of the model have been disappointing as it assumes that periodic cash flows are independent of each other. Zavgren, C. It is not possible here to review in detail the enormous number of empirical studies.

Although Lev touched on these matters, it was not until Lev and Sunder that the full ramifications were examined. More services and features.

Pohlman, R. This allows to link your profile to this item. According to Joy and Tollefson a more appropriate statistic would indicate that it was the least impor- tant. These include: the assumptions of multivariate normality irf the distribution of the sample groups, the equality of the group dispersion variance-covariance matrices, addressing the problems of determining the zyxwv relative importance of individual variables, reducing the number of variables that do not significantly contribute to the overall discriminating model, the selection of prior probabilities and costs of misclassification, and the classifica- tion error rates.

However, for pro- prietary reasons these are not usually disclosed. Bird, R.

## Comparative ratio analysis

Zmijewski, M. This instability increased over time as the firm neared failure. Dombolena and Khoury found a substantial amount of instability in the financial ratios as measured by their standard deviations and their coeffi- cients of variation in the ratios of firms which went bankrupt compared with those that did not. In empirical research, control for size effects is done by, for example, dividing the examin- zyxwv ed ratio by industry mean ratios. That is, when making inferences concerning corporate performance relative to the industry as a whole was demonstrated there was a larger proportion of the population classified incorrectly compared with a better fitting t 2 approximation. Horrigan used correlation analysis, while Pinches and Mingo used MDA to predict published corporate bond ratings by means of individual ratios. Each ratio was analysed separately and the cut-off point selected so as to maximise the number of accurate classifications for a particular sample. According to Joy and Tollefson a more appropriate statistic would indicate that it was the least impor- tant. Concerning the former, the traditional approach was to transform the data in such a way so that it eventually conformed. Dombolena, I. Foulke, R.
