# Research Lab

> Player trends, defense vs. position rankings, pairwise correlation analysis, custom betting lines, and what-if scenario simulations across leagues.

The Research Lab is the deeper analysis surface — for when you've found a prop you're interested in and want to understand the player, the matchup, or the correlation structure before placing.

## Analysis modes

<CardGroup cols={2}>
  <Card title="Player Analysis" icon="user">
    Single-player deep dive. Performance trend, rolling hit rate (10-game window), and our combined probability estimate alongside the implied probability from current odds.
  </Card>

  <Card title="Defense vs. Position" icon="shield-halved">
    How teams defend specific positions in specific stat categories. "Lakers rank 28th vs Point Guards in Assists" — that's the data point.
  </Card>

  <Card title="Correlation Analysis" icon="diagram-project">
    Pairwise correlation between players' stat lines. How does Luka's points relate to Kyrie's assists? Heatmaps and scatter plots over the last 20 games.
  </Card>

  <Card title="Team SGP" icon="layer-group">
    Same-game-parlay construction informed by team-level historical correlation data.

## Auto-insights

Each player + prop combination generates auto-insights:

* **🔥 Hot / ❄️ Cold** — significant deviation from season average over the last 5 games
* **🏠 Home Advantage** — meaningful home/away split for this player
* **🛡️ Defensive Matchup** — opponent ranks top-5 in defense against this position
* **📊 Matchup History** — how the player has performed historically against this specific opponent

These appear as colored cards above the chart so you can scan the situational context without reading every datapoint.

## Custom betting line

Enter any specific over/under threshold (e.g., 25.5 points) to instantly see:

* Hit rate over the last 20 games against that specific line
* Home/away split at that line
* A reference line drawn on every chart so you can see where each game landed

This is useful for any prop that's not at our default — say, the line opened at 24.5 and is now 26.5, and you want to know which side actually has historical support.

## Probability scenarios

The "What If" simulator lets you adjust input variables and see how the probability estimate moves:

* **Driver stat slider** — change Luka's points from 25 to 35 and see how it propagates to Kyrie's assists, the team total, etc.
* **Pace adjustment** — model a faster or slower game tempo
* **Minutes adjustment** — what if a player gets blowout minutes vs. a normal load

NBA has the deepest support because that's where we built first and where the historical data is densest.
