Analiza regresji dla liczby systemów i placówek franczyzowych w Polsce
The regression analyasis for the number of franchise systems and units in Poland

Summary/Abstract: The purpose of the paper was to examine how the aggregate number of franchise systems affects the number of franchise units in Poland. The paper initially outlines the term of franchising and sectors, dominating in the franchise market in Poland. Then, for the years from 2004 to 2011, the linear and exponential regression models were built, taking as an independent variable X the number of franchise systems and as the dependent variable Y the number of franchise units. For this purpose, the regression models parameters are determined, i.e., the regression coefficient, the constant term and on the base of them the regression functions were built. Then set the mean square error and the goodness of fit coefficient. There has also been done the prediction of number of franchise units at the end of 2012 and 2013, by the assuming the value of independent variable X and the predicted standard error. In the conclusions referred to the determined parameters of regression models. It was found that an exponential regression model is more appropriate to describe the researched population
