Factor Analysis

Statistical method that models observed variables as linear combinations of latent factors plus noise

Factor Analysis

Statistical method that models observed variables as linear combinations of latent factors plus noise.

When to use:

  • Believe data has underlying latent factors
  • Need probabilistic model
  • Want to model noise explicitly
  • Social science / psychometric data
  • Need factor interpretation

Strengths: Probabilistic model, models noise, interpretable factors, handles missing values Weaknesses: Assumes Gaussian noise, slower than PCA, can be unstable

Model Parameters

N Components (default: 2, required) Number of latent factors.

Max Iterations (default: 1000) Maximum EM algorithm iterations.

  • 1000: Usually sufficient
  • 2000+: For difficult convergence

Tolerance (default: 0.01) Convergence threshold.

  • 0.01: Standard (default)
  • 0.001: Stricter convergence

Random State (default: 42) Seed for reproducibility.
