Abstract

Background: Some variables like socioeconomic status (SES) cannot be directly measured, instead, so-called ‘ latent variables’ are measured indirectly through calculating tangible items. There are different methods for measuring latent variables such as data reduction methods e. g. principal components analysis (PCA) and latent class analysis (LCA). Objectives: The purpose of our study was to measure assets Index-as a representative of SES-through two methods of Non-Linear PCA (NLPCA) and LCA, and to compare them for choosing the most appropriate model. Methods: 􀀃 􀀷 􀁋 􀁌 􀁖 􀀃 􀁚 􀁄 􀁖 􀀃 􀁄 􀀃 􀁆 􀁕 􀁒 􀁖 􀁖 􀀃 􀁖 􀁈 􀁆 􀁗 􀁌 􀁒 􀁑 􀁄 􀁏 􀀃 􀁖 􀁗 􀁘 􀁇 􀁜 􀀃 􀁌 􀁑 􀀃 􀁚 􀁋 􀁌 􀁆 􀁋 􀀃 􀀔 􀀜 􀀜 􀀘 􀀃 􀁕 􀁈 􀁖 􀁓 􀁒 􀁑 􀁇 􀁈 􀁑 􀁗 􀁖 􀀃 􀂿 􀁏 􀁏 􀁈 􀁇 􀀃 􀁗 􀁋 􀁈 􀀃 􀁔 􀁘 􀁈 􀁖 􀁗 􀁌 􀁒 􀁑 􀁑 􀁄 􀁌 􀁕 􀁈 􀁖 􀀃 􀁄 􀁅 􀁒 􀁘 􀁗 􀀃 􀁗 􀁋 􀁈 􀁌 􀁕 􀀃 􀁄 􀁖 􀁖 􀁈 􀁗 􀁖 􀀃 􀁌 􀁑 􀀃 􀀷 􀁈 􀁋 􀁕 􀁄 􀁑 􀀑 􀀃 􀀷 􀁋 􀁈 􀀃 􀁇 􀁄 􀁗 􀁄 􀀃 were analyzed by SPSS 19 (CATPCA command) and SAS 9. 2 (PROC LCA command) to estimate their socioeconomic status.

LCA is a complicated method that presents detailed information about latent variables and required one assumption (local independency), while NLPCA is a simple method, which requires more assumptions. Generally, NLPCA seems to be an acceptable method of analysis because of its simplicity and high agreement with LCA.
