Replace our utilities for parsing version strings with `packaging.version.Version`? https://packaging.pypa.io/en/latest/version/# https://stackoverflow.com/questions/11887762/how-do-i-compare-version-numbers-in-python To confirm expected behavior, try swapping it into our unit tests first.

This issue is to lay out a strategy for handling primary outputs of model steps vs. derived variables, vs. potential secondary outputs that are _not_ derived variables. Tagging @mxndrwgrdnr and...

We are starting to accumulate template-specific dependencies, like PyLogit for Small MNL and Scikit-learn for Random Forest. At the moment, many of these model types are not used very often....

Template for random forest models

I'm setting up an issue for the random forest template that @Gitiauxx is working on! Tagging @waddell and @Arezoo-bz for feedback and additional guidance on use cases for the template....

Formats for persistent storage of configured model step instances

1

How should we balance dict-based and binary representations of configured model step instances? This topic was raised by @gitiauxx. Writeup based on discussion with @janowicz and @sablanchard. ### Pros and...

Currently there's a parent class that most templates inherit from, called "TemplateStep". This was intended to reduce code duplication, but it hasn't been very useful because the inputs and data...

Automated out-of-sample validation of estimation results

2

This is a feature proposal to support automated out-of-sample validation of fitted models, across all the statistical templates. For example, a user could fit a model using 2/3 of the...

UrbanSim notebooks often begin with a command to change the Python working directory. This is clunky and annoying, and breaks if you accidentally run the cell more than once. Surely...

Add "notes" field to saved model steps

1

This is a feature proposal to add a free-form `notes` field to saved model steps, alongside the `name` and `tags`. Originally suggested by @sablanchard. This would be particularly useful in...

There's been a feature request to add latex export for summary tables. ### OLSRegressionStep This uses the core UrbanSim regression class, `urbansim.models.RegressionModel()`. We save the model object for interactive use,...
