The core concepts behind every Sportslyx page, explained without jargon: probability versus prediction, expected value, the market as a public estimate, sample size, and how to build a model you can actually test.
Guides
15 guides in this category, newest first. Each one is tied to the pages it refers to — the hub, the statistics section, the pick tracker — so the method can be tested on live games rather than taken on trust.
How to analyze a VALORANT series: the rotating map pool, the veto, compositions, roster changes, reading the series line, and how a one-map loss is graded.
Strokes gained explained: what it measures, why it beats scoring average, which components persist, and how course fit and the outright market shape a preview.
How to build a sports model: pick the question and inputs, avoid leakage, turn ratings into probabilities, calibrate against the market and run it live.
What expected goals measure and miss, why the confirmed goalie moves an NHL line, shot share, special teams, puck line versus moneyline and overtime grading.
How to analyze a Dota 2 series: best-of-two, three and five formats, what the draft and a new patch change, rosters, reading the series line, and grading.
How to analyze a soccer match with data: the 1X2 market as a probability, why the draw changes the math, expected goals, form, and grading a draw as a push.
Why the starting pitcher drives an MLB moneyline, ERA versus FIP, strikeout and walk rates, bullpen fatigue, platoon splits and park factors, explained.
How to analyze a UFC fight with data: style matchups, significant strikes, takedown defense, finish rate, reach and layoffs, and how a fight read is graded.
How to analyze a Counter-Strike 2 series: best-of formats, the map veto, map pools and rosters, reading the series line, and why a one-map loss is a push.
An NBA statistics guide for analysis: per-possession ratings, the four factors, pace, rest and availability — which numbers predict and which only describe.
A repeatable way to analyze an NFL game: read the line first, weigh the injury report, use efficiency over yardage, account for rest and wind, then grade it.
Expected value explained with real prices: the formula, break-even probabilities by American odds, the vig, correlated legs, variance and realized ROI.
What sports analytics is, how it differs from statistics and prediction, why the market is the baseline, and how to judge any model on its record.

What This Section Covers
Sports analytics is not a collection of clever statistics; it is a way of asking questions so that the answers can be checked. The guides in this category cover the concepts that recur on every sport page of this site — what a probability means, how a price becomes a probability, what expected value is and is not, why a descriptive statistic can look predictive and fail, and how much data it takes before a result means anything.
They are written for readers who want to understand the method rather than be handed a verdict. Each concept is illustrated with a worked example using real market prices, and each is connected to the way Sportslyx actually behaves: the market-derived win probability on every game, the flat-stake ROI in the public record, the one-calendar-month period used across the product, and the grading rules that decide how a draw or a scratched player counts.
The longest guide in the category walks through building a sports model step by step — choosing inputs, converting ratings into probabilities, calibrating against the market, and running the model live so it can be graded. It maps directly onto Studio, where a stat-weighted model can be run on live games and every run is saved and scored.
