  • Investigate and prepare data for analysis • Identify suitable variables for predicting a target variable • Select predictor variables that fit given criteria • Create training and validation datasets • Select appropriate algorithms to model datasets • Train models • Compare models • Interpret model reports • Score new data with trained models • Classification • Regression • Time series • Optimization

Note:

  • Arima/ETS can specify the starting period
  • logistic regression tool must have only 2 values for target variables
  • Optimization tool:
    • Manual input:
      • objective: function to minimize/ optimize
      • constraint: constraint of the function of variable
      • Bound: range of possible value of the variable
    • O anchor (listed vertically), [”variable”] [”coefficient”]
      • • The order of variables for input O and input A must be the same.
      • Display field mapping for input anchor to map the field
      • variable for the objective function (no inequality because we always want to optimize the coefficient)
    • A anchor (constraint matrix using the combination of variables from O anchor)
      • Constraints in rows (preferred): one row one constraint, [var1] [var..] [”dir”] [”rhs”]
      • Variables in rows: one row one var (need dir & rhs as input B) [’variable’] [factor]
    • maximize Onjective?: default to be minimize if this option is not ticked
