Walks plus Hits per Inning Pitched = (BB + H) / IP
ERA
Earned Run Average (using 4 innings as standard game length) = 4 * (ER / IP)
FIP
Fielding Independent Pitching measures how well a pitcher pitched independent of his team's defense by taking into account home run, walk, and strikeout rates.
More details about the exact FIP formula used is available.
xFIP
Expected Fielding Independent Pitching is the same as FIP except, instead of using raw home run rate, the league-average HR/F is used to estimate how many home runs the pitcher should have allowed (the assumption being that some part of home runs given up is purely luck).
TTO%
Three True Outcomes Percentage is the percentage of plate appearances that result in one of the three defense-independent batting events: home runs, walks, and strikeouts.

Batting Average on Balls In Play = [H - HR] / [AB - K - HR + SF]. BABIP is mostly an indicator of the pitcher's defense. A relatively high BABIP indicates a poor defense.

Isolated Power Against estimates hitters' raw power against a pitcher. The PECOTA formula, which weights doubles and triples evenly ([2B + 3B + (3 * HR)] / AB), is not used here because only doubles and triples are a poor indicator of power in wiffleball. [(3 * HR) / AB] is used here instead.
