Forecasting, also known as prediction, is the art and science of estimating future events.

What are the three types of forecasting horizons?

The three forecasting horizons are short-term, medium-term, and long-term.

What is the naive forecasting approach?

The naive approach assumes that future demand will be the same as the most recent demand.

How many steps are involved in the forecasting process?

There are seven steps in the forecasting process.

What are the main types of forecasting?

The main types of forecasting are economic, technological, and demand forecasting.

What is the significance of trend projection in forecasting?

Trend projection involves using past data to predict future trends, which is crucial for long-term planning.

What are the four components of time series data?

The four components are trend, seasonality, cycles, and random variation.
