Menganalisis Kasus Heywood pada Variabel Manifes

Setelah Anda melaporkan temuan, kelompok adopsi membuat ulang survei mereka untuk mengukur dua faktor: seberapa efektif unggahan cerita online mereka pada goodstory dan seberapa penting interaksi inperson. Data baru dimuat dalam adoptsurvey. Dalam latihan ini, Anda akan mencari kasus Heywood pada salah satu variabel manifes, bukan pada variabel laten.

Pemodelan Persamaan Struktural dengan lavaan di R

Petunjuk latihan

Analisis data terbaru adoptsurvey untuk model dua faktor adopt.model dengan fungsi cfa().
Perhatikan peringatan setelah cfa() dijalankan.
Gunakan fungsi summary() untuk menelusuri variabel manifes mana yang bermasalah.

Latihan interaktif praktis

Cobalah latihan ini dengan menyelesaikan kode contoh berikut.

# Build the model
adopt.model <- 'goodstory =~ pictures + background + loveskids
inperson =~ energy + wagstail + playful'

# Analyze the model and include the data argument
adopt.fit <- cfa(___)

# Summarize the model to view the negative variances

In this chapter, you will dive into creating your first structural equation model with lavaan. You will learn important terminology, how to build, and run models. You will create a one-factor model of mental test abilities using the classic Holzinger and Swineford (1939) dataset.

Exercise 1: Model Specification Exercise 2: Build Text Speed Model Exercise 3: Build Political Democracy Model Exercise 4: Model Analysis Exercise 5: Analyze Text Speed Model Exercise 6: Summarize Political Democracy Exercise 7: Model Assessment Exercise 8: Examine Standardized Loadings Exercise 9: Explore Fit Indices Exercise 10: Examine Political Democracy

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.
