GSCA Pro is free software for generalized structured component analysis (GSCA), which is a component-based approach to structural equation modeling (SEM). This software provides a graphical user interface that allows users to easily express their model as a path diagram and view results. 

GSCA Pro 1.1 enables users to

• conduct a single- or multiple-group analysis 

• evaluate and compare overall and local model fit 

• constrain parameters within a group or across groups

• consider second-order components

• analyze discrete indicators (nominal or ordinal)

• include component interactions 

• apply regularization (ridge or lasso) 

• conduct a multilevel analysis 

• consider components and factors simultaneously

• conduct a mediation and conditional process analysis

• handle missing observations

• calculate descriptive statistics
