On January 22, 23, and 26, our colleague, Professor González-Romá, taught an online course on “Multilevel Modeling with SPSS” to a group of professors from the Department of Business Administration at Istanbul Bilgi University (Turkey). The course began with an explanation of the logic behind these models. A sequence of increasingly complex models was then explained: from a basic model with random intercepts that allows for the decomposition of the variance of the dependent variable, to a model that includes predictors at different levels and random intercepts and slopes. Finally, the course explained how to estimate these models using SPSS and included exercises in defining multilevel models adapted to different research questions.
