Bangun Model Demokrasi Politik

Sekarang Anda dapat memperluas keterampilan spesifikasi model ke himpunan data baru. Buat sebuah model untuk penilaian Demokrasi Politik tahun 1960 menggunakan himpunan data PoliticalDemocracy. Himpunan data ini mencakup penilaian politik di negara berkembang pada era 1960-an.

Variabel y1, y2, y3, dan y4 mengukur kebebasan pers, kebebasan oposisi politik, keadilan pemilihan, dan efektivitas legislatif. Anda harus membuat model dengan satu variabel laten bernama poldemo60, dan empat variabel manifes.

Exercise 4: Analisis Model Exercise 5: Analisis Model Kecepatan Teks Exercise 6: Ringkas Political Democracy Exercise 7: Penilaian Model Exercise 8: Periksa Loading Terstandarisasi Exercise 9: Jelajahi Indeks Kecocokan Exercise 10: Menelaah Demokrasi Politik

In this chapter, you will expand your skills in lavaan to creating multi-factor models. We will improve the one-factor models from the last chapter by creating multiple latent variables in the classic Holzinger and Swineford (1939) dataset.

Exercise 1: Multifactor Specification Exercise 2: Create a Zero df Model Exercise 3: Fix the Zero df Model Exercise 4: Build a Multi-Factor Model Exercise 5: Summarize the Multi-Factor Model Exercise 6: Model Structure Exercise 7: Three-Factor Model with Zero Correlation Exercise 8: Create a Direct Path Exercise 9: Modification Indices Exercise 10: Check Model Variance Exercise 11: Examine Modification Indices Exercise 12: Model Comparison Exercise 13: Compare Two Models Exercise 14: Select Specific Fit Indices

Structural equation models do not always run smoothly, and in this chapter, you will learn how to troubleshoot Heywood cases which are common errors. You will also learn how to diagram your model in R using the semPlot library.

Exercise 1: Heywood Cases on the Latent Variable Exercise 2: Analyze a Latent Heywood Case Exercise 3: Fix the Latent Heywood Model Exercise 4: Heywood Cases on the Manifest Variables Exercise 5: Analyze a Manifest Heywood Case Exercise 6: Fix the Manifest Heywood Model Exercise 7: Create Diagrams with semPaths()Exercise 8: Basic SEM Diagram Exercise 9: Edit the Layout Exercise 10: Edit the Labels

This chapter examines the WAIS-III IQ Scale and its structural properties. You will use your skills from the first three chapters to create various models of the WAIS-III, troubleshoot errors in those models, and create diagrams of the final model.

Exercise 1: Model the WAIS-III IQ Scale Exercise 2: Create a Four-Factor Model Exercise 3: Update the Model Exercise 4: Diagram the Final Model Exercise 5: Update the WAIS-III Model Exercise 6: Add Paths to Improve Fit Exercise 7: Compare Models Exercise 8: A Hierarchical Model of IQ Exercise 9: Create a Hierarchical Model Exercise 10: Diagram the Hierarchical Model Exercise 11: Course Wrap Up
