Lecture 6

Question 1

-Confirmatory factor Analysis

Answer 1

Determine whether a predetermined factor model fit the data (Which indicator should load on which factor)

Question 2

Requirements of Confirmatory factor Analysis

Answer 2

1-Requires strong prior knowledge concerning the factor structure
1- How many factors are there
2- Whether the factors are correlated
3-Which items load on which factors?

Question 3

Double/cross- loading

Answer 3

when and item loads on multiple factors at the same time.

Question 4

Advantage of confirmatory factor analysis?

Answer 4

1- Hypothesis testing
2-fewer parameter to estimat ( prior knowledge)
3- rotation is not necessary
4- flexible ( correlated residuals, second order factor)
5- standard erros and goodness of fit measure ( test weather the factor loadings are statistically signiifcant, test the model statistically)

Question 5

Dis advantages of CFA?

Answer 5

1- requires strong prior knowledge
2- requires dedicated software.
