Live HBSGrid Demos

July 9, 2020

Software modules have arrived on the HBSGrid! The modules provide users with flexible access to multiple versions of software (e.g., Python 2.7, Python 3.6, etc.), software in home folders and project folders, and settings defaults for specific projects. One no longer has to use only the software version that was previously installed on the Grid.

On Tuesday, July 14, at 2 PM, Bob Freeman will present a special live demo on how to start using these modules, how these will work in NoMachine, and best practices around their use. No registration is required...

If you had used a local R install (== miniconda in your home folder), to transition to the central one, you'll need to do the following:

New Tip from the RCS Stats Team

May 17, 2019

This month's tip is by our Senior Statistician, Xiang Ao: 

Stata’s margins command has been a powerful tool for many economists. It can calculate predicted means as well as predicted marginal effects. Sometimes we’d like to compare those marginal effects. People use margins and marginsplot to generate marginal effects; then draw conclusions on whether there is a difference between marginal effects, based on whether the confidence intervals overlap or not.
