Interactive Logit Model

Adjust parameters to see their influence on exit choice probability.

NPCs choosing Left Exit:

NPCs choosing Right Exit:

Fire Warden Present:

Yes

Warden Directs Towards: Left Exit Right Exit

Warden Authority Level: Metro Staff Firefighter

Calculated Results:

Utility of Left Exit (V_L): 0

Utility of Right Exit (V_R): 0

Probability of choosing Left Exit (P_L): 0%

Probability of choosing Right Exit (P_R): 0%

0%

Left Exit

0%

Right Exit

Model Parameters & Formula

V_Left = β_NPC * NPC_L + β_I * I_L + β_FF * FF_L
V_Right = constr_R + β_NPC * NPC_R + β_I * I_R + β_FF * FF_R

• Intercept for Right Exit (constr_R): 0.263
• NPC coefficient (β_NPC): 0.035
• Warden Presence (β_I): 2.739
• Warden is Firefighter (β_FF): 0.559

Where:

• NPC_L/R: NPCs at Left/Right Exit.
• I_L/R: 1 if warden present & directs Left/Right.
• FF_L/R: 1 if warden present, directs Left/Right, AND is firefighter.
