Hi folks,
Just wanted to share my latest blog post on using some rudimentary digital signal processing techniques to examine the patterns in New Eden: http://newedenanalytics.blogspot.com/2014/07/applying-digital-signal-processing-to.html
I plan on delving more into this in future posts, but wanted to share this primer.
Cheers,

As sine is odd, and cos is even, every function can be expressed as a sum of sin and cos functions.
...so?
Gotta start somewhere (-: |

cosine is just sine phase shifted by pi/2 So really any periodic function can be represented as a sum of sine or cosine waves.
Aww, don't go off ruining my whole next post on Fourier Transforms ;-) |

Sibyyl wrote:Hi Calvin, thanks for posting your analysis. About your article Jump Pattern Analysis, how did you get data of number of jumps?
I have a script that auto-collects from both the Jumps and Kills APIs every hour, it's been running ~1.5 months now, so lots of data to work with (-: |

We live all across an oblate spheroid, orbiting a giant ball of fire, of course its cyclical.
Sorry but what's your goal here?
Curiosity (-: |

Tweaked sine functions match the cosine shape of activity in New Eden. Conclusion: EvE is like a fine symphony. The wave shapes are near perfect. Or something else. I would like to see the results when downtime is done away with...as is planned.
Tell me about it, that 'hiccup' skews the data for at least three hours :-/ |

Wendrika wrote:Ack! Math! My only weakness! How did you know?!
Personaly, I would just use multi-linear regression and hope for the best. Maybe toss a few variables like, I dunno, number of people online versus the population of Amarr at a given hour. But then I'd have to check collinearity to make sure both variables are independent and...
Gosh, I really hate Math! I don't need Sine Waves!
Actually that's where I started, but I got annoyed that I needed all these discrete variables to account for time. I wanted a better way, hence where the sine wave stuff came in. Ideally I want a formula to convert all of the time data into a linear function so I can only use one variable to capture all of the time-based variance. Something of a pipe dream, but even with the messive amounts of data I have, I don't have enough to properly analyze the game on all the dimensions I want to. |
