Could Bigfoot be real?

Reminds me of the self-proclaimed geneticists a year or two back who claimed to have sequenced the Bigfoot genome. They published their results in a real-life peer-reviewed journal, even! That, uh, they founded. And which published a grand total of one paper.

Oh, and their published genome sequences were clearly a mixture of human, bear, and known non-human primates.

In Texas he would need a license and there might be a bag limit.

But OTOH, "The claim is being made by Oxford University’s Bryan Sykes, already well-known for his research on human ancestry. Sykes says his findings suggest that sightings of the legendary Yeti may actually represent observations of a previously unknown creature in the Himalayas — perhaps a hybrid of polar bears and brown bears.

Sykes told NBC News that his aim is to bring the Yeti out of the realm of myth and fantasy. “All my colleagues think I’m taking a risk in doing this, but I’m curious, and I am in a position to actually do something to answer the questions,” he said.

*Outside experts didn’t reject Sykes’ conclusion out of hand. Tom Gilbert, professor of paleogenomics at the Natural History Museum of Denmark, told The Associated Press that Sykes’ research provided a “reasonable explanation” for past Yeti sightings. *"

Not too much woo coming from the hard scientists at Oxford.

In fact “unknown or mis-idenified bear” has been the legit mainstream scientist* possible explanation* for decades.

Well hold on to your hat, because I’m going to present some more multivariate work. That’s stat-speak for “More than 2 explanatory variables”.

We looked at bigfoot sightings above and saw they were related to population. Then we looked at the scatterplot. Washington State was a big outlier and we think we know what was going on: that’s where Mr. Foot’s legend began. That outlier is going to exert a big effect on measuring the other variables’ effect on bigfoot sightings. So let’s take it out.

In fact, let’s take at all states in the Pacific Northwest. That will tell us where Bigfoot prefers to go on vacation, a well defined problem. I could simply drop them from a sample, but if I construct a variable for each NW state -Washington, Oregon and California- we’ll be able to see the effects of each. So let’s do that:

There’s a lot of gobbledygook above, but I want the reader to focus on the P>|t| column: if it’s less than .05, that means the variable is statistically significant (at the 5% level). Population matters a lot. Washington State is a huge outlier and Oregon is pretty big as well. California, not so much - insignificant.

But the more interesting variable in per capita income - states outside of the NW with higher income per person (after controlling for state population) tend to have fewer bigfoot sightings. The coefficient (size of the effect) is negative and the t-stat/P-value indicate statistical significance. Mr Foot is a man of the people!
Now I can present a little mischievousness. I know that Red States tend to be poorer than blue states on average. So it wouldn’t surprise me if there’s a (spurious) relationship between the Romney share of the vote and bigfoot sightings, after controlling for population. And sure enough, there is:

Note that I removed out per capita income and replaced it with Romney vote. What’s happening is that the red state effect is confounded by the poorer state effect. Or maybe Bigfoot loves Romney! To sort out this pressing issue, we need to include all the relevant variables: otherwise we will have what’s known as omitted variable bias. Let’s correct the problem by including Romney and per capita income:

Per person income and population remain statistically significant. Share of Romney vote drops to insignificance - though it’s still positive, possibly reflecting the bucolic nature of reddish states.

Looks like he’s real, and from Mars.

So all these years Bigfoot has just been campaigning?

Like Pat Paulson.

I miss The Smothers Brothers. They satirized political lunacy so well. Way ahead of their time. Jon Stewart and Colbert are their modern incarnation. Both wickedly funny. Anybody else notice how un-funny conservatives are ? Republicans have no one close to these guys. And don’t tell me Bill O’rielly’s sidekick, what’s his name, is even close.

Peer reviewed article tests Bigfoot hair samples and matches them to bears, wolves and cows. Also coyotes, raccoon, sheep, porcupine, horse, deer, and even human. Two hair samples from the Himalayas matched with ancient specie of polar bear. Yeah, the article was written by Syckes.

Secondary source:

“Species” is singular.

The Army has the remaining Bigfoots on a secret reservation so they can study their amazing gift of stealth.
