Předpoklady
! PSY544 Introduction to Factor Analysis
Students are strongly recommended to have taken at least an elementary course in statistical data analysis. Solid understanding of multiple linear regression is beneficial, as is at least basic knowledge of R. Students with zero or little previous exposure will be given resources and time to catch up and will be expected to do so.
