Forecasting Accuracy Metrics: Our Guide
Dive into our latest report and navigate the world of Forecasting Accuracy Metrics with confidence. This blog post outlines essential metrics that any data science professional should master to accurately predict future business trends and outcomes. Stay ahead with our updated insights on key forecasting accuracy metrics, helping you drive smarter business decisions.
Simple forecasting metric: Uses the average of past data points for predictions; simple but lacks trend and seasonality capture.
Weighted Moving Average: Assigns more weight to recent data for better trend capture, requires less historical data.
Seasonal Decomposition Of Time Series
Decomposition Metric: Separates time series into trend, seasonal, and residual parts, improving accuracy by considering seasonality.
Autoregressive Integrated Moving Average
ARIMA Model: Combines AR and MA models, along with differencing for stationarity, to forecast based on past-present relationships.
SARIMA: Extends ARIMA with seasonal differencing and terms, ideal for seasonal time series.
Triple Exponential Smoothing: Adds trend and seasonality to exponential smoothing for forecasting time series with trends and seasonality.
Multivariate AR Model: Extends AR to multiple time series, ideal for simultaneous forecasting of multiple series.
Bayesian Structural Time Series
Probabilistic Bayesian Model: Enhances accuracy by incorporating uncertainty and external data, suitable for limited historical data.
Croston’s Method: Designed for irregular, intermittent demand forecasting by separately predicting demand size and intervals.
Neural Networks: Al and ML for complex, large-scale time series forecasting with learned patterns.
Facebook’s Forecasting: Handles irregular trends, seasonality, and holidays using automatic model selection.
Time Series Decomposition
Time Series Decomposition: Breaks down data into components (trend, seasonal, etc.) for accurate forecasting.
