Regression Analysis

Statistical technique that examines relationships between variables

Primarily quantitative

Doesn't specifically focus on accidental events or their consequences

More for prediction than risk treatment evaluation

B$.$ Trend Analysis

Examines patterns over time

Can be both qualitative and quantitative

Not specifically designed for analyzing consequences of accidents

More for identifying patterns than evaluating risk treatments

C$.$ Event Tree Analysis

Forward logical modeling technique that identifies possible outcomes following an initiating event

Analyzes consequences of accidental events by showing how safeguards and external factors affect accident progression

Provides both qualitative $($sequence identification$)$ and quantitative $($probability calculation$)$ analysis

Specifically designed to evaluate effectiveness of preventive measures and risk treatments

Widely used in risk management to assess system safety

D$.$ Decision Tree Analysis

Helps make choices between alternatives

Can be both qualitative and quantitative

More focused on decision$-$making than specifically analyzing accident consequences

Used for decision support rather than specifically for risk treatment evaluation
