A Guide on Dynamic Parameter Estimation for Causal Forecasting


Tanmoy Bhowmik


Executives now-a-days rely on forecasting approcahes in virtually any decision making. The use cases are ubiquitous in business and technology domains ranging from Demand/Sales forecasting in Supply Chain Management, Hiring/Attrition rate forecasting in HR operations, Predicting the cell traffic or netwrok health parameters for a Telecom business, just to name a few. The challenges faced in forecasting in general, are mainly because of inherent non-linearity and non-stationarity in the time series. In this talk, I will try to walk through a systematic approach for parameter estimation in forecasting of time series data with causal factors available in the light of statistical estimation theory.


  1. Forecasting Overview : Time Series based and Causal Forecasting
  2. Linear Estimation :
    i. Deterministic Estimation : Best Linear Unbiased Estimator and Sequential LSE
    ii. Bayesian Estimation : Sequential LMMSE and Kalman Filter
  3. Nonlinear Estimation : Extended Kalman Filter and Sequential Neural Network
