arm-ssa

Singular spectrum analysis to detect outliers in ARM data. This is a univariate analysis method. You need to pick the variable first.

  1. Calculate outliers and visualize the results
  arm-ssa.py: python arm-ssa.py
  # Figures are stored in ssa-figures and ssa-figures-outliers
  1. Query DQR database
  db.py: python db.py
  # Results are stored in db.records
  1. Visualize outliers in Plotly
  arm-ssa-plotly.py: python arm-ssa-plotly.py
  # Figures are stored in plotly
