To calculate the Rating Percentage Index (\(RPI\)):
\[ RPI = 0.25 \times WP + 0.5 \times OWP + 0.25 \times OOWP \]
Where:
RPI, short for Rating Percentage Index, is a metric used in college basketball, and sometimes the NBA, to rank or determine the strength of a team based on their winning percentage and their strength of schedule. The strength of schedule (SOS) includes both the team's direct opponent winning percentages and the winning percentage of their opponent's opponents.
Let's assume the following values:
Using the formula:
\[ RPI = 0.25 \times 0.75 + 0.5 \times 0.60 + 0.25 \times 0.55 = 0.625 \]
The Rating Percentage Index is 0.625.
Let's assume the following values:
Using the formula:
\[ RPI = 0.25 \times 0.80 + 0.5 \times 0.70 + 0.25 \times 0.65 = 0.725 \]
The Rating Percentage Index is 0.725.
