Time series analysis in loan management information systems

A loan management information system (for transaction processing in credit institutions) records data for given loans, returned sums for principal, interest and taxes. The purpose of this article is to accept or reject our assumption that the more loans are given, the more sums are returned by customers. The main methodology used is time series analysis. Data are analyzed in SPSS. The main proved conclusion is that incoming money flows in credit institutions do not depend on the amount of given loans. This article is published for the first time. This article gives notes for extending existing loan management information systems for loan management in credit institutions and banks in the direction of business analysis.
