Scatter Plot Madness!

Today I made 60 different scatter plots attempting to relate different measures of spinal degeneration to range of motion. 

The best one had an r^2 value of 0.59. So basically I would conclude that none of these variables individually correlate to range of motion, except that my sample size is so small, I don't think I have the statistical power to prove the negative hypothesis. So in fact I can conclude nothing.

All that means I tried the simple statistics and nothing worked. So now I try some more complicated stuff. I think this is called statistics hell.

US Politics

I've been following the American presidential primary race (maybe a little too) closely. Despite what the conventional media makes it sound like, the race for elected delegates is all but decided. Obama built up such a huge lead that Hillary can't catch up unless she wins every remaining state with a greater margin than she has won any other state in this entire primary race. And some of the states remaining are predicted to go to Obama.

However, after all the primaries, neither candidate will have enough elected delegate votes to win the nomination at the convention so the decision will ultimately be made by the super-delegates. They are free to vote any way they choose (as opposed to elected delegates that must vote according the primary results). But if they choose to give the nomination to Hillary, the party will effectively overturn the will of the people. I don't think this will happen because it will fracture the Democratic party and alienate all the citizens that voted for Obama. Disenfranchisement of that magnitude will likely cost the democratic party the November election. An election that currently looks preordained for the democrats to win.

Yet, Hillary is still competing. Some people think that she is either deluded enough to think she can still win the elected delegate race or will use her (and her husband's) political clout at the party convention to convince enough super-delegates to give her the nomination. I think people in the party are aware of the potential consequences and wouldn't go for it, but I don't think that is what Hillary is trying to do. I don't think she is trying to win any more and instead she is trying to raise money.

At the beginning of April, Hillary's campaign was 15-million USD in debt (including a 5-million personal loan Hillary made to the campaign) with 9-million cash on hand. So negative 6-million in total. But a campaign can't raise much money after it has given up. So since the time that it became a foregone conclusion that Obama would win, I think Hillary has been making it look like she is fighting like hell, to inspire people to continue donating money and hopefully get her campaign out of the red.

A lot of Obama supporters want her to give up because they think that Hillary's “kitchen sink” strategy has been hurting him and the Democratic Party's chance of eventually winning the general election. But I think that if Obama wanted to, he could put enough political pressure on Hillary to make her quit now. I think he wants Hillary to keep running (no matter how negative she goes) because:
  • The longer the primaries keep going, the more popular he becomes. Even in Pennsylvania (where he lost) he held his biggest rally to date. I've read estimates ranging from 20,000-40,000 people attended to listen to him give a stump speech. 
  • During these primaries many states have recorded record voter turn-out. And regardless of whether they vote for Hillary or Obama now, they will mostly vote democrat in November.
  • As long as the Democratic primaries keep going, it dominates the US news, and the Republican party is marginalized. 
  • Right now Obama is campaigning as if he were already the nominee, mostly addressing McCain but McCain doesn't have a forum to reply. Nor can McCain continue campaigning until the primaries are over because his primary budget is gone. He can only access the rest of his money after the primaries are over, and the presidential race begins.
In the end it all comes down to the money, and while the primaries continue, it is an advantage that Obama can exploit.

Spring has sprung

In less that a week I've observed the following changes, all on the walk to and from the train station and the lab each day.
  • The daily high temperature is about 10-15 degrees warmer
  • Birds are singing again
  • There are little lizards running across the path
  • Leaves and flowers on every plant are blooming
  • I walked past a couple having sex next to a construction dumpster
I think it's all pretty conclusive.

Techno music and matlab

So if you haven't seen me around too much lately it's because I've been (nearly) living in my office for about the last two weeks. I'm really pressing to get some results for one of the projects that make up my master's thesis. I'm using a math program called matlab to analyse a bunch of x-rays of geriatric subjects flexing and extending their necks. I'm trying to correlate different measures of degeneration to the spine's range of motion. So far all my results suck. (R^2 values of around 0.1 for anyone out there who knows a little statistics.)

It's pretty frustrating and I think I'm a little too emotionally invested in this work. But I keep reminding myself that this is just the nature of research and I keep trying to mash these variables together in slightly different ways. At least coding is fun. I'm not kidding! I'm really enjoying figuring out all these little logic problems and learning new functions while I get this to work.

Since I've been staying late and eating at my desk every day, it's given me a chance to listen to a lot of new music. I find band recommendations from Pitchfork Media and then listen to the music using Deezer. While coding I've been listening to a lot of "Boards of Canada". One of my favourites also happens to have a really cool video.

A little sunshine

Today I am in noticeably better spirits than I have been lately. I think this is the direct result of:
  • Today it was sunny (it's been cold, dreary, and occasionally stormy the last few weeks)
  • I rode my bike to work, instead of taking the train (the first exercise I've had in over a month)
  • Veronica made chicken soup that tasted exactly like the soup my mom makes
  • I ate a lot of the aforementioned soup

healthy but still hideous

I just wanted to give a quick update let you know that I'm feeling much better. I have been all week and I'm now off all of the antibiotics I was taking. Unfortunately, my tiny eye devil is still with me. One month later this stupid stye, just won't go away! I've been seeing the doctors regularly (with surprisingly little difficulty from my Canadian health insurance) and the current theory is the infection must have been killed by the antibiotics and now it's just inflammation.

So now while I go put some more cortisone cream in my eye, I leave you with this hilarious video by Björk. I was hooked as soon as I saw the cat in the wife-beater, and seeing the cat dance sequence at the end is worth the wait.

sick again

Really! Unless it's some joke my immune system is pulling on me. At least I'm not flat on my ass but it's enough to make dragging myself to work miserable. It's really getting me down. I can not believe how sickly I've been these last few months. I don't know what's wrong.
