# Variable Selection (+2)

## Variable Selection


1. **Primary variable** - Choose the most critical response
2. **Linked variables** - Include relevant causative factors
3. **Physical correlation** - Select variables that explain the extreme


## Time Range


1. **Exclude ramp-up** - Skip initial transient period
2. **Statistical period** - Use 3-hour simulation for design
3. **Multiple seeds** - Consider seed variability


## Reporting


1. **Context** - Include simulation parameters
2. **Units** - Always specify units
3. **Uncertainty** - Note seed sensitivity if applicable
