The Rising Star Algorithm
The algorithm is the core of InnoBors. It is a sliding window over 90 days (variable=$SlidingWindow) creating a "value", the rising star index for a company.
Input parameters
The RSI (rising star index) is calculated from
- expert score ($ExpertScoring)
- total Invest (k) - $TotalInvest
- new invest (in the period) - $NewInvest
- number of Comments (in the period) - $Comment
- total Thumbs up - $Thumbs
- new Thumbs up (in the period) - $NewThumbs
- Random numbers to avoid "inverse engineering" - $RANDOM
- Delay since Børs-Introduction - $BorsEntry
Based on the algorithm below, the RSI is calculated.
algorithm
- SlidingWindow = 90 days
- The RSI is updated every night at 02:41h, thus users will not see an immediate effect, but only an update the next day
- RSI= INT( 2.6 $ExpertScoring/50
- + 2.1 $TotalInvest/20000
- + 8.9 $NewInvest/20000
- + 2.1 $Comment
- + 1.8 $Thumbs
- + 4.3 $NewThumbs
- + $RANDOM
- + $BorsEntry )
Mathematical operations
- INT = create integer of number , e.g. INT(50.3)=50, INT(2.7)=3
- $RANDOM is a random number between 1 and 5
- $BorsEntry = 24 - Number of Month since entry, ($BorsEntry > 0)
- Example: Entry: Oct2011 Date: Feb2012 -> $BorsEntry=20
- Example: Entry: Oct2010 Date: Feb2012 -> $BorsEntry=8
- Example: Entry: Oct2009 Date: Feb2012 -> $BorsEntry=0
