Analiza log-liniowa jako metoda wyboru czynników opisujących aktywność turystyczną gospodarstw domowych emerytów i rencistów

The article attempts to select variables which influence the decision to go on holiday in pensioners’ households. The information on tourist activities of pensioners’ households has been taken from the survey entitled Tourism and Recreation in Households, conducted by the Central Statistical Office (GUS) in 2005. A log-linear analysis was used for the purpose of selecting the optimal set of factors determining the decision to go on holiday, as categorical variables were taken into account in the study. As a result of testing the interactions between all the variables it turned out that apart from main factors the interactions maximum of the third rank should be included to a log-linear model. The factors which most often interact with other variables include: children’s presence in a household and the unemployed, possessing a recreation plot and a car.
