API

All arguments are sanitized e.g.:

• invalid inputs are treated as zero (0) e.g. null, undefined, non-numeric strings, etc.
• decimal values are dropped

In the case of zero player deaths, it is raised to 1 when performing the computations e.g. Math.max(d, 1).

Kill Ratios

kda(k, d, a)

k

Type: number

The number of player kills.

d

Type: number

The number of player deaths.

a

Type: number

The number of player assists.

Computes the Kill-Death-Assist ratio (KDA), the higher it is from 1, the better the player's performance.

Dominance Statistics

df(k, d, a)

k

Type: number

The number of player kills.

d

Type: number

The number of player deaths.

a

Type: number

The number of player assists.

Computes the dominance factor (DF) which is a point sum, where each kill progresses the sum by 2, each assist progresses the sum by 1, and each death regresses the sum by 3.

Participation Statistics

kp(k, a, tk)

k

Type: number

The number of player kills.

a

Type: number

The number of player assists.

tk

Type: number

The total number of a team's kills.

Computes the Kill Participation ratio (KP) which measures a player's involvement in fights or duels across a given game, and is defined as the percentage ratio of the sum of kills and assists, over the team score.
