Sorry, I'm not 'looking for work' as in handing out resumés, looking for a 9-5. The acquisitions are in the 7-figures. But I am always looking for new opportunities -- new startups to work with, etc. I do really like your poi

Grade inflation has really made these inferences even more difficult; for example, the median grade at Harvard is actually an A- (not the well-balanced distribution you hypothesized).

This post is almost entirely inaccurate re: actual statistics. Power, as you say, is the likelihood of a given experiment rejecting the null hypothesis given some a priori sample size and effect size. And one- vs. two-tailed tests do not ch

It's good to be critical, but you need to evaluate on a case-by-case basis or you risk never learning anything new.

While I agree that it is unreasonable to expect someone to deeply understand the current state of all of these technologies/problems, an actual "full stack engineer" needs only to be able to learn very quickly about these

Re: power law distributions. I'm not sure what you mean about finite versus infinite variance. Are you referring to whether you are analyzing a bounded versus unbounded scale? Even if a scale is unbounded, that still wouldn't make

I should also add... you can also use median absolute deviations, standard deviations, or interquartile ranges to identify and remove outliers who you think don't reflect your business's true status. But it all depends on what you

I'm not sure I follow this, or buy into the suggestion of the post. First, I don't see how it's true that data with a relatively large amount of variance will tend to be power law distributed. Defining what a "large amou

But, by talking about the "other factors", you are just re-configuring the group from which one would assess your individual probability of having a heart attack. You're right that group statistics aren't meaningful when the individual is n

Ok. In related news, I tried to measure the length of a day the other day (just to make sure we're not being had) and it was 29 hours long! My watch was broken, but still - 29 hours! Could it be that some days are 29 hours long? We'll never

There have been countless attempts at observing telepathic-like phenomena and not a single one has produced anything. I'm not sure why you are saying science claims not to know about telepathy. Every scientist I know would claim it doesn't

His talk is filled with nonsense. In the beginning, I was going along with him ("yes - let's challenge scientific assumptions") but from the point at which he said rats can learn essentially telepathically, I was out. And it just got worse

He says the speed of light fluctuates, but the scientific community simply says its constant by definition.

by brockf 14y ago
You literally have no idea what you're talking about. I can't even argue with you because you clearly do not understand the definition of science, and so we're talking past each other. "Replication is nearly unheard of?" Are you kidding? Re

Also, by this logic, neither gravity nor string theory are scientific. You can't weigh them! Or define their location!

This is wrong on so many levels. Psychology uses indirect measurements of cognitive/behavioural phenomena just like particle physicists. This idea of "real" versus "pseudo" (or "soft", as some people say) science is intuitive but does not h

You should really talk to some cognitive scientists for some depth and perspective on the issues of studying the mind. There are real things to consider about the study of the mind, predisposition and plasticity, dynamic systems versus symb

I think you may be thinking of the relationship between down syndrome and maternal age, which I have heard estimated at "thousands of times more likely". However, perhaps this is a slight exaggeration as well: http://pregnancy.about.com/c
