Introduction to Assumptions

How Assumptions are used to store Model inputs

PreviousData TypesNextCreating/Referencing Assumptions

Last updated 10 months ago

Overview

In , input values are stored separately from and their .

This allows you to manage the inputs to your Model independently of the calculations within the Model, and to easily create variations on your inputs (through and ).

This separation means that you can create sets of Assumptions from scratch, without creating the Variables that will reference them, though in practice you will most often generate Assumptions from within a Variable as this is by far the fastest way to do so.

The Assumptions Tab

Keeping Assumptions separate from Variables means you can thoroughly interrogate and quickly edit all inputs to your Model in one place.

You can do this in the Assumptions Tab, where functionality includes (as per the above screenshot):

  • Search and Order your Assumptions with Tag filters, text search, property filters and sorting (1)

Selecting a single Assumption will show you a preview including the details of that Assumptions Unit; Selecting multiple Assumptions will show you a chart (if the selected Assumptions' Units can form a valid series)

Directly edit Assumption values (2) - just click in a cell, type, and press Enter to save

Directly edit Assumption values (3)

Visualise your assumptions in - just select any Assumptions that relate to each other, and Models will plot them on a chart which you can configure.
