📖 Explanation
LB_CI:Lower bound of a 95% confidence interval, calculated on the full
dataset. This metric is chosen because it provides a conservative
estimate of player performance, accounting for variability in the
data.
MEAN:Calculated by summing all values and dividing by N, representing the average performance metric across all players.
MAX:Maximum value of the metric, indicating the highest performance
achieved in the dataset.
N:Number of players in the dataset, providing the sample size for
statistical calculations.
Score:Official Blizzard Mythic+ Score from the API, reflecting the
performance rating as determined by Blizzard's metrics.
Tiers are formed by distributing specs using the Ckmeans algorithm, which is chosen for its optimal one-dimensional clustering capabilities.
Specs are binned in clusters (tiers) based on the LB_CI value.
This algorithm is particularly effective for datasets where the goal is
to create distinct, non-overlapping groups based on a single variable,
in this case, the LB_CI value.
The algorithm ensures optimal and deterministic clustering results,
meaning tier boundaries remain consistent when run multiple times with
the same data. The number of clusters is 5: S,
A, B,
C, D, with
each tier representing a different level of performance.
