2 algorithms in PHP (simple php, no frameworks) to make calculations for song positions in a music chart. A bit approximation is allowed. I don't give any particular deadline, my priority is accuracy and price, according to the deadline you choose.
I'm 15y experienced PHP developer, looking for statistics and math skilled developer.
Testing dataset will contain some full charts:
• songs and positions
• number of sells for some songs
ALGO 1:
hyperbolic chart (see the attached picture)
ALGO 2: TSF + EMA
PHP modules like [login to view URL] are allowed.
TSF (time series analysis) for predicting the position for tomorrow.
EMA (exponential mobile average) for mitigating trend invesion.
The algo should be based on track history (and artist history? generic track trend?). If you haven't ever managed this stuff before, please don't make any offer.
No advanced milestones will be released.
PRIORITIES:
PRIO 0 - the algorithms.
PRIO 1 - graphic representations (jquery, I use Highcharts)
PRIO 2 - SEARCH field with auto complete
