Factor Analysis: 2 Types – Confirmatory & Exploratory

LET՚S BEGIN! !

Exploratory Factor Analysis

  • Measure underlying factors affecting the variables in a data structure without setting any predefined structure to the outcome
  • Not based on prior theory

Confirmatory Factor Analysis (2 Types)

  • Confirm predefined components already explored
  • Implemented for reconfirming the effects and possible correlations existing between a set of predetermined factors and variables
  • Larger sample size
  • Produces inferential statistics

Traditional Approach

  • Based on principle factor analysis rather than common factor analysis
  • Knows more about factor loading
  • Factor loading - Relation of each variable to the underlying factor. Output of a simple factor analysis looking at indicators of wealth, with just six variables and two resulting factors
  • 6 variables: Income, education, occupation, house value, public parks and crimes
  • 2 factors: individual socioeconomic status and neighborhood socioeconomic status
  • Factor Score – if value of variables are given then factor values can be predicted

Structural Equation Modeling

  • To formulate a relationship between a set of variables and factors and measures causal relationship using linear equation model.
  • Can be used for confirming result under scrutiny and testing predicted outcomes
