Statistics in Engineering: Linear Regression (Part 2 of 8)

Preface
This series is aimed at providing tools for an electrical engineer to gain confidence in the performance and reliability of their design. The focus is on applying statistical analysis to empirical results (i.e. measurements, data sets).

Introduction
This article will introduce linear regression on a data set using the R Project software. This is useful if your data is "on a line" rather than a Gaussian distribution.

I Don't Believe in Dark Matter

I think dark matter is an awful explanation for an explanation of the "missing matter" problem. We can't see it? Oh it must be invisible?!? Lame.

I have another idea and it is much more simple. It starts with the basic question: What if the gravitational effects come from beyond the edge of our universe?

A couple of points of evidence and a concept appropriated from astronomy:

Product Verification for Electronic Hardware

I recently wired my lab for ethernet and began automating my testing with Python scripts and the awesome Python(x,y) environment curated and maintained by Google. Freed from the burden of so much test setup this got me thinking about how to design and execute a test which fully and accurately characterized the unit under test. This is broken into the following objectives:

A Proposal For A Determinism That Is Compatible With Free Will

I've always thought that the world is strictly deterministic and causal. Study physics for ten minutes and it just seems so obvious that for every 'thing' that exists there is a physical counterpart. All the particles in the universe, our thoughts in our brains and if there is a god then it too would have a physical component.

A Better Way to Shop

I have been shopping online for many years now and I was thinking about the things I buy online and the things I buy in the store. Sometimes I buy things in the store because I sought advice and other times I buy online because the price was just too good. But with services like Zappos, Amazon Fresh and Google Shopping Express I am beginning to wonder if there is a future left for brick and mortar retailers. This way of shopping is going to usher in a shift in the way we shop and buy goods. How can retailers compete?

If You Can't Beat Them, Join Them

I had a funny thought yesterday on the way home from work. I was thinking about a quote that went something like "politicians follow the money, not the idea". And I thought no, there is always an idea behind the money. It's just that wealthy groups get their way, get their ideology into law because they have the money. In other words they are represented but the vast majority of Americans are not. I do agree it is unfair that the distribution of representation in government matches the wealth distribution and not the population distribution. So if that is the case, how do you fix it?

Fragments, Existential

I haven't posted much lately, mostly because I've been busy but also because I've been reading existentialist text and it has completely flipped my understanding of the world on its head. It's as if all of creation was obsessed with the person from the Universe's point of view until Kierkegaard came along and asked what the world was from the Person's point of view. Nevertheless I decided to write down a few thoughts that have been rolling around in my head for some months.

United States Post Office (USPS) Shipping Chart

I have always found the shipping options at the USPS confusing, so I did some research and made this chart to help.

How Good Is A Philosophy?

How good is a person's philosophy? Of all the famous philosophers, which had the best work? And how good is my philosophy?

That is the central thesis of my thought lately. If I were to measure each philosopher's work how would I do it? How can I develop a philosophy which is better than the one I have now and how could I prove that it is?
