Types of Factor Analysis
  • Exploratory Factor Analysis (EFA)
  • is used to discover the factor structure of a
    construct and examine its reliability. It is
    data driven.
  • Confirmatory Factor Analysis (CFA)
  • is used to confirm the fit of the hypothesized
    factor structure to the observed (sample) data.
    It is theory driven.

9
Structural Equation Modeling (SEM)
  • Structural Equation Modeling (SEM) techniques
    such as LISREL and Partial Least Squares (PLS)
    are second generation data analysis techniques

10
Data Analysis Techniques
  • Second generation data analysis techniques
  • SEM
  • PLS, LISREL
  • statistical conclusion validity
  • First generation statistical tools
  • Regression models
  • linear regression, LOGIT, ANOVA, and MANOVA

11
SEM models in the IT literature
  • Partial-least-squares-based SEM (PLS-SEM)
  • PLS, PLS-Graph, Smart-PLS
  • Covariance-based SEM (CB-SEM)
  • LISREL, EQS, AMOS

12
The TAM Model
13
Structured Equation Modeling (SEM)
  • Structural model
  • the assumed causation among a set of dependent
    and independent constructs
  • Measurement model
  • loadings of observed items (measurements)on
    their expected latent variables (constructs).

14
Structured Equation Modeling (SEM)
  • The combined analysis of the measurement and the
    structural model enables
  • measurement errors of the observed variables to
    be analyzed as an integral part of the model
  • factor analysis to be combined in one operation
    with the hypotheses testing
  • SEM
  • factor analysis and hypotheses are tested in the
    same analysis

  • The holistic analysis that SEM is capable of
    performing is carried out via one of two distinct
    statistical techniques
  • 1. covariance analysis employed in LISREL, EQS
    and AMOS
  • 2. partial least squares employed in PLS and
