The SciSkill index is designed to provide an indication of a player's skill level for scouting purposes. It does so by measuring the influence of a player on his team. The SciSkill is computed on a per-match basis. The SciSkill is able to calculate the influence that the player has on the team he plays for. The input variables of the SciSkill information are:
- Number of minutes a player played in a particular position;
- Type of match (e.g. league, cup, international);
- Strength of the league and the opponent;
- The number of goals scored and conceded by the player's team.
The algorithm determines the skill level of a player based on historical information. A player's SciSkill is based on his performances in matches, where more recent matches are more relevant ("have a higher weight") than older matches.
