There are series of forecasting techniques, u can use ARIMA, ETS, artificial neural network, random forest etc. It all depends on the nature of your data.
Common forecasting techniques in time series analysis include ARIMA (AutoRegressive Integrated Moving Average), Exponential Smoothing (e.g., Holt-Winters), Vector Autoregression (VAR), Seasonal Decomposition, and Machine Learning methods like Random Forests and Neural Networks.
Here’s a brief explanation of common forecasting techniques used in time series analysis:
ARIMA (AutoRegressive Integrated Moving Average): Combines autoregressive (AR) models, moving average (MA), and differencing to make the series stationary. It’s widely used for short-term forecasting.
Exponential Smoothing (e.g., Holt-Winters): This method weights past observations exponentially, with more recent data given more weight. It’s useful for series with trends and seasonality.
Seasonal Decomposition of Time Series (STL): Breaks down a time series into trend, seasonal, and residual components, helping to understand the underlying patterns.
Vector Autoregression (VAR): A multivariate model used for forecasting multiple time series simultaneously, useful when variables influence each other.
Machine Learning Techniques: Methods like Random Forests, Support Vector Machines, and Neural Networks can be used for non-linear time series forecasting, particularly when there are complex patterns beyond simple statistical models.
These methods can be applied based on the nature of the data and the forecasting horizon.
