About This Feature

Overview

GAMMAINV is a built-in statistical function in WPS Spreadsheet for Windows. It is used to return the inverse of the gamma cumulative distribution in worksheet calculations and analysis. After you enter the formula, you can combine it with cell references and let results recalculate automatically when source values change.

Core capabilities include:

Use the GAMMAINV function directly for probability distribution calculations.
Enter flexible parameters for different calculation scenarios.
Combine cross-sheet references and nested formulas in one worksheet model.
Keep results updated automatically after related data changes.

Common use cases include statistical analysis, classroom exercises, and experiment data processing.

System Requirements

Item	Requirement
Operating system	A Windows device that can run WPS Office normally
App version	WPS Spreadsheet is supported across available versions; using the latest WPS Office release is recommended
Network	No mandatory internet connection is required for local formula calculation
Other	You need permission to open or create spreadsheets and edit cells

Download & Installation

Before using GAMMAINV, install WPS Office and open the Spreadsheet component.

Capability Summary	Provides the GAMMAINV statistical function with parameter input, cross-sheet references, nested formulas, and automatic recalculation in spreadsheet cells.	Excel provides GAMMAINV and GAMMA.INV for returning the inverse of the gamma cumulative distribution.	Google Sheets provides GAMMA.INV for the inverse gamma cumulative distribution and notes that `GAMMAINV` can also be used.	Notion formulas work with database properties, built-ins, and functions, but the official help page does not describe a spreadsheet-style GAMMAINV equivalent.	Acrobat supports calculated PDF form fields such as sum, product, average, minimum, and maximum, which fits form workflows rather than spreadsheet statistical functions.
WPS Advantages	Advantage: Enter the function directly in worksheet cells, combine references, and keep results recalculated as data changes in a spreadsheet workflow.	Compared with WPS: supports the same category of function and documents both legacy and newer naming.	Compared with WPS: supports the same type of inverse gamma calculation, with official examples centered on `GAMMA.INV`.	Compared with WPS: better suited to database property formulas and automations than cell-based statistical analysis.	Compared with WPS: better suited to PDF form calculations than worksheet-based distribution analysis.

Overall Conclusion: If you need inverse gamma distribution results inside spreadsheet cells with references and automatic recalculation, WPS fits a familiar worksheet workflow. Notion and Adobe provide calculation features for different product types, so they serve different use cases rather than the same spreadsheet function scenario.

Use Cases

No.	Scenario	Suitable for	Main challenge	How WPS helps
1	Statistics practice	Students and teachers	Need to verify inverse gamma distribution results quickly	Enter the GAMMAINV formula in a cell and review the result directly
2	Experiment data analysis	Researchers	Need to repeat calculations for multiple parameter sets	Use cell references and fill formulas across ranges with recalculation
3	Model parameter checks	Data analysts	Need to place a statistical function inside a larger formula	Use nested formulas to combine GAMMAINV with other calculations
4	Multi-sheet analysis	Finance or operations analysts	Source values are stored on different sheets	Use cross-sheet references to pull parameters into one formula
