Standard Deviation Differences Between Excel and R (and my code in Cube Voyager)
http://www.siliconcreek.net/computers/standard-deviation-differences-between-excel-and-r-and-my-code-in-cube-voyager
Laquo; Running Python in Atom.io in Windows. R OMX County Flows. Standard Deviation Differences Between Excel and R (and my code in Cube Voyager). I had a need to get the correlation of count to assignment in Cube Voyager. I don't know how to do this off the top of my head, and I'm instantly mistrusting of doing things I'd normally trust to R or Excel. So I looked on Wikipedia for the Pearson product-moment correlation coefficient. And ended up at Standard Deviation. Just for fun, I did the same in Excel:.
Quick R Trick: Lists and Data Frames
http://www.siliconcreek.net/computers/quick-r-trick-lists-and-data-frames
Laquo; "If there were Internet slow lanes, you'd still be waiting". Using R with Phant. Quick R Trick: Lists and Data Frames. I didn't know something better to call this, but you can use lists with data frames as variables to hold multiple field names:. Temp=maz[,MIN] #temp is now a data frame of all rows with just NAICS21, NAICS22, and NAICS23. Temp=maz[,c("TAZ",MIN)] #temp is now a data frame of all rows with just TAZ, NAICS21, NAICS22, and NAICS23. Comments from Other Sites. Beer and Running Website.
Alternatives to Word?
http://www.siliconcreek.net/management/alternatives-to-word
Laquo; Iterating Through DBFs - R Style! Planes, Trains, and Automobiles. It has been a while. Mostly because we're preparing for a peer review and still making adjustments to the model. The one thing more frustrating than that: Word 2013. So my break-off from a forced hiatus is this: what else is out there? Posted on Friday, April 4th, 2014 By Andrew Rohne Comments are closed.

Using Variance and Standard Deviation in Trip Rate Checks
http://www.siliconcreek.net/travel-modeling/using-variance-and-standard-deviation-in-trip-rate-checks
Laquo; Frustrations with ArcObjects. Nice, Quick, Effective Sampler in R. Using Variance and Standard Deviation in Trip Rate Checks. During the peer review, one thing that we were told to look at was the variance in the cells of our cross-classification table. Like all statistics, variance needs to be looked at in context with other statistics. To illustrate this, I created some fake data In Excel. The first thing I looked at was the variance compared to the mean. What does this mean? They're a little be...
Nice, Quick, Effective Sampler in R
http://www.siliconcreek.net/travel-modeling/nice-quick-effective-sampler-in-r
Laquo; Using Variance and Standard Deviation in Trip Rate Checks. Improved Nice, Quick, Effective Sampler in R. Nice, Quick, Effective Sampler in R. It's always good to test models. In the best case, we'd test models against a different dataset than what we used to develop data. In not-the-best-but-still-not-that-bad of cases, we'd use 80% of a dataset to estimate a model, and 20% of it to test against. These will ultimately be part of something larger, but so far, so good.

Another New Year’s Goal Post / State of the Ham | KE8P.US
http://www.ke8p.us/general-stuff/another-new-years-goal-post-state-of-the-ham
Another New Year's Goal Post / State of the Ham. Jan 7, 2015. This is two out of four for me. I'm too busy. So last year I had a number of things I wanted to do. Then my radio went kaput and I still haven't fixed it. Other things happened, too. This year I am definitely going to fix. or pay someone to fix my IC-706. I will probably get into FreeDV and maybe another digital voice mode. I want to build a receiver, too, and not from a kit. I've been somewhat silent out here, but that shall change soon.

RFduino and the Physical Web. Jan 14, 2015. I happened to stumble on an advertisement for a cool looking device that would work with a phone via Bluetooth. It was ideally something that would be used for things like movie times, bus waiting times, or something else small and URL based. kinda like a QR code without the annoying camera part. So I got a pair of RFduinos. The library comes with an example program accessible under File-Examples-RFduinoBLE-AdvertisementContinuous. Where This Is Going. Rather t...
Shark | KE8P.US
http://www.ke8p.us/tag/shark
Repair of a Shark Steam Mop. Mar 15, 2015. WifE8P was complaining that her Shark Steam mop was not producing a lot of steam. That's really the only way we clean the dining room, kitchen, and entry floors, so it's pretty important for it to work. The steam would act like it was operating, but would put out little steam. This is actually pretty easy to take apart. The only tool required is a Philips screwdriver, and there are few clips. This was the problem – a pebble made it up to the outlet nozzle.

General Stuff | KE8P.US
http://www.ke8p.us/category/general-stuff
Category Archives: General Stuff. May 21, 2016. In terms of success, this ranks up pretty high. I wheeled-and-dealed on everything, and I feel like I made out like a bandit! I didn't stay very long at Hamvention - I arrived around 8:30 AM and I was gone by around 1:30 PM. Astron VS-20 Power Supply. It works. I needed a power supply for my bench, and everything new was either adjustable (but not powerful and expensive) or powerful and expensive. This is better than I thought I'd end up with. But for some ...

Dayton Shopping List | KE8P.US

Apr 28, 2015. Hamvention is at a busy time for me, and I didn't know if I was going to attempt to go or not. I think I'm going to go, though, because I need stuff. New NMO mobile antenna setup. I'm not looking for any real radio equipment other than parts. I have some specific needs (linear-taper variable resistors, etc), but nothing out of the ordinary. Arduino/Raspberry Pi/Beaglebone Black stuff. Because you can't have too much! Click to share on Twitter (Opens in new window). Andrew is the owner of th...

Am I right or wrong?
