Introduction to the RMS Package. February 5, 2017. We start this introduction to the rms package with the datadist function, which computes statistical summaries of predictors to automate estimation and plotting of effects. The user will generally supply the final data frame to the datadist function and set the data distribution using the options function. Note that if you modify the data in your data frame, then you will need to reset the distribution summaries using datadist. This may not seem like any...

The Meaning of Traffic. Asymp; Leave a comment. The great thing about traffic is that it mostly is not the government’s problem. It’s all of our problem. Last month I spent nearly a thousand dollars on brakes, and this morning I noticed a new Low Tire Pressure Light . This is the cost of doing business. In America. The quickest way for a family to get out of poverty in many cities is to get a car. The whole appeal of motorized traffic at the turn of the 20. To this day almost all transit agencies operate...

America, 1776 | HeadWater Solutions
https://headwatersolver.wordpress.com/2014/07/03/america-1776
Asymp; Leave a comment. So, for the 238th Independence Day, I thought I’d get a handle on what the United States looked like in 1776. A map-making company in England with the resources to get good maps of the original 13 colonies printed a map for the public interest during the War . The details on these maps are pretty icy, and make me wish I had time to get precise referencing on them. I’d like to figure out how to open source this. Larr; Previous post. Next post →.

The Point of Walking. Asymp; Leave a comment. This July Fourth almost didn’t happen. It has been a rainy spring and summer, the rainiest I can remember. I recall most July 4th weekends as brutally hot and sunny. The settling dark before the fireworks was usually a relief from the heat of the day. But not this 4th. This day started in a pleasant shower, overcast, then an afternoon downpour. It was drizzling by sundown. Then I heard a boom. Larr; Previous post. Next post →. Leave a Reply Cancel reply.
