New #article out in Environmental Modeling & Software with Oliver Gao & colleagues @CornellSystems ! TLDR: We built MOVESLite, a short-form model of the @EPA 's MOVES #emissions estimator! @iEMSsNews @CornellEng #transportnews @rstats_tweets

Need suggestions for how to estimate a model with MLE given different sized inputs, preferably in #R. (From scratch is fine.) (Eg. 14 obs for X1, 70 different level obs for X2, Y data for both.) Any ideas or resources I should look at? @RCoderWeb @rstats4ds

Check out our piece in Urban Climate on mapping social infrastructure with Google Map's API! Fantastic working with colleagues @DanielPAldrich, @Timothy_Fraser1, and @Northeastern graduate students on this project! #socialcapital

My new #article from @JJPS_Eds: How social infrastructure saves lives: a quantitative analysis of Japan's 3/11 disasters
TL;DR: Investing in social infrastructure would save more lives than putting the same money into standard, gray infrastructure

As a new EV owner, wondering, why must I get rained on when using the charging station, when the gas pumps next door all have rain covers? 🌧️ Slight implementation problem. But yay EV!

A new research with @ChapmanLabo and @Timothy_Fraser1 was out from Energy Res. Soc. Sci.. This study elucidated the drivers of social equity factor underlying the renewable energy transition across the nations, which we quantified in the previous study. https://t.co/ZKUN5SOaJ1

Chai-squared - the tastiest statistic. 🧋

Love to visualize your models in #RStats , but sad that @zeligproject is no longer on CRAN? Check out my simulate package on Github! Easy @tidyverse style simulation!

Our #article mapping #Boston's social infrastructure is out in Urban Climate! with @DanielPAldrich, @CourtneyPageTan, and our students! @CornellRsrch @CornellSystems @NUPoliSci @NU_PolicySchool
TLDR; Google Maps can measure social infra pretty reliably!

@Anthro_CAM Did this over Zoom during the pandemic. Things that worked:
- Breaks!
- Divide into groups with questions, have groups present answers to class.
- Labs: students try out technique for 30-40 min, then share findings.
- Break class into regular pieces, to set expectations
