Multiple – Equation Models of Ordered Dependent Variables in Exploration of The Results of Rehabilitation of Locomotive Organ Disorders

In the present paper concerning the analysis of the factors determining patient’s self-service during the admission and release from hospital a two-equation model of ordered dependent variables is proposed. These types of models are especially useful when the results of rehabilitation of locomotive organ disorders are not described by means of exact values obtained by mechanical measurements but they are described by means of qualitative valuation (ranking) made by a therapist when the distances between neighbouring ranks are not known. The advantages of the proposed model were presented on the basis of the results of estimation based on data of 4063 patients of hospitals from Mazowieckie and Warmińsko-Mazurskie provinces.
