The Breakpoint Detection Tool is designed to identify significant changes in time series data. By uploading a CSV file containing both date or time and numerical values, users can quickly pinpoint where trends in their data shift.
The tool runs statistical tests, specifically the Chow test, to determine if a change is statistically significant. Once the test is complete, users are presented with a plot showing the data, including trend lines before and after the detected breakpoint. This can be highly useful for businesses and researchers analyzing data over time, such as sales trends, stock market performance, or environmental data. By identifying breakpoints, organizations can better understand shifts in patterns, allowing them to make more informed decisions based on clear data trends.
