4.5 Regression AnalysisIn the previous section the focus was on measurement of the relationships between thevariables. Here the research is taken a step further. In regression analysis we fit a model toour data and use it to forecast the value of the dependent variable from the one or moreindependent variables. This research uses multiple regression analysis (more than onepredictor) to determine the value of the dependent variable.To determine the influence of transformational leadership, transactional leadership,bureaucratic culture, innovative culture and supportive culture on organizational commitmentthe researcher conducted a regression analysis. The model for this research contains amediating variable which intervenes in the relationship between the independent and thedependent variable, the stepwise procedure developed by Baron and Kenny (1986) was usedto test for mediation of organizational commitment The following regressions were analyzed:Step 1Leadership variable –Transformational – (independent, IV) and control variablesagainst Organizational Commitment (dependent, DV)IV M DVOC=Constant+ 1 TF+ 2 Gender+ 3 Function+ 4 Age+ 5 Education+ 6 Salary+ 7 ServiceStep 2 Leadership variables, Culture variables (independent, IV) and control variablesagainst mediating variable Job Satisfaction (M)IV M DVJS=Constant+ 1 TF+ 2 TA+ 3 BC+ 4 IC+ 5 SC+ 6 Gender+ 7 Function+ 8 Age+ 9 Education+ 10 Salary+ 11 Service36
