What is moving weighted average method?

Moving Weighted Average Method

Definition

The moving weighted average method is a technique used in data analysis and forecasting to calculate an average value by assigning different weights to different data points. It gives more importance to recent data points and less importance to older data points.

Calculation

The moving weighted average is calculated by multiplying each data point by its assigned weight and then summing up the weighted values. The weights are typically predetermined and can be based on factors such as time period or significance of the data point.

Weighting Scheme

The weighting scheme determines the relative importance of each data point in the calculation of the average. It can be linear, exponential, or based on other mathematical formulas.

Application

The moving weighted average method is commonly used in various fields, including finance, economics, inventory management, and demand forecasting. It helps in smoothing out fluctuations in data and identifying trends.

Lagging Indicator

Like other moving average methods, the moving weighted average is a lagging indicator, meaning it reflects past data and may not immediately respond to changes in the underlying data.
