### Re: 1357: "Free Speech"

And what about getting fired from your job** for things you say and do in your private life? Funny how that one is not mentioned. (**reading people's minds in advance: Fine. Being forced to resign under pressure...as though that is different.) Randal was quite clear about this in the first box. The...

### Re: Bugs popping up only under optimization

Thanks for pointing out the problems in my code! I figured someone would correct me in short time. And yes my indentation is terrible. Code written in between other tasks (not coding) so I wasn't paying much attention.

### Re: Bugs popping up only under optimization

I have some code with this bug. I'll post it at the end. It is basically code to simulate a lottery. You set what numbers to match and you test to see how many times you get the numbers you ask. I loop through the process 10x the expectation. So the probability is about 1 in 76767600 so I loop 76767...

### Re: 1292: Pi vs. Tau

It really bugs me this obsession with the arithmetic mean. Everyone knows the compromise solution should be (approximately): 4.44288293815836624701588099006069369861462168937569022308539560695643479309947391057532693476476523736341021268522879136435959851834562749237534635967441502327927881975587753...

### Re: 1132: "Frequentists vs. Bayesians"

XKCD should be officially renamed "Me So Smart". This strip can be amusing at times but for the most part it's just incredibly pretentious. Some say it used to be better. Maybe. All I know is that now it seems like the purpose of most of the strips is for the author to let us all know how...

### Re: p<0.05 is very bad

I think one of the central things to take away from this cartoon is the notion that deciding on significance (or truth) with a p value of < 0.05 is all too common yet a p value of < 0.05 is only as common as rolling a double six (or any double so long as you select which double you want first). Its ...

As a current Boston resident, along with Randall, I can attest to the fact that he may be referring to any number of intersections in the Boston area. I'm always amazed at how few accidents happen in Boston. I think its because the confusion that is sowed by the traffic "rules" and "i...

### Re: US Mega Millions Lottery Jackpot reaches $500 Million

Yeah, I'm pretty sure your odds are just as good when buying ABCDE and ABCDF as when you buy ABCDE and FGHIJ, since the sequences of numbers are all unique and have an equal chance to pop up. Let's say there are 2 letters drawn from 4, A B C and D. The possible combinations are AB AC AD BC BD CD Or...

### Re: Why standard deviation?

The Gaussian is everyone's favourite distribution because it shows up all over the place, especially coming out of the central limit theorem. Macbi is right, but I'd like to point out that other distributions also show up all over the place. The Gaussian is not everywhere . While you can measure th...

### Re: Is a random walk a sufficient model of the stock market?

Ah yes, that works wonderfully, thank you. Can you post your latest equation you are using? The method I was testing actually seems to be performing better in this model (except for a rounding error where the exponent shifted by over 75000 in one step, and the program suggested buying infinitely ma...

### Re: Is a random walk a sufficient model of the stock market?

So it sounds like I would do better using something like: -1 < r_i < 1 x_{i+1} = x_i + \frac{x_i}{a}\cdot(\frac{1}{r_{i}}-sign(r_i)) And thanks for the reading suggestions. This is an interesting model but it has a couple of problems. I plotted an example run, using as a start: x = ...

### Re: Is a random walk a sufficient model of the stock market?

As the above reply says, fractal models do a better job of modelling stock markets. When one plots price changes in a histogram, most would probably expect a Gaussian distribution. In fact, if the stock market was a random walk, price changes would be Gaussian. However, the histogram appears to obey...

Using e instead of [imath]\pi[/imath] we can do:

Lovely!

14e/19 is closer.
