ordinal regression; delays in payment

Sažetak
We have analysed delay of payments towards suppliers in shipyard „Brodosplit“ in Split, Croatia. Delay of payments was ordered into four groups: 0-60 days, 61-90 days, 91-120 days and over 120 days. Several predictors were proposed at the beginning of the study. Those variables are different suppliers regarding the sort of materials they offer. The first one was “ML” which represents the most expensive material whose potential suppliers are the shipyard and the ship-owner. Variable “A” is composed of direct materials which need further analysis of the offers. Variable “N” is standard material which is specified by the list of materials whose term of delivery is within 60 days. Variable “ZM” is also standard material which is specified by special demand whose term of delivery is over 60 days. Variable “L” is the list of materials whose assortment and quantity is limited by catalogue at the annual level. Delay of payment was treated as dependent ordered variable and we used ordinal regression. Predictors were dichotomous whose modalities were “yes” or “no” which depends if supplier is on the list or not. Reference category for dependent variable was last one: terms of payments over 120 days as the longest one. Applying ordinal regression we have found two variables to be statistically significant: ZM (p = 0, 002) with the estimate of regression coefficient of -3.524 and L (p = 0, 075) with the estimate of regression coefficient of -1.051. All statistics in ordinal regression were sufficient and significant and this model could be regarded as good for prediction. References: 1. Hosmer, David W. and Lemeshow, Stanley (1989).
