Grunk give example with outlier. Three options: A score 5, B score 3, C score 1. Softmax makes probs: A big, B medium, C small. If one person has weird taste (outlier) add big random term to C score so C chosen often by that person. Mixed models handle this.

Grunk teach. Logit simple: each option gives score (utility). Higher score, more chance to be picked. Difference turned into probability by softmax (so all probs sum to 1). Easy to compute and fast. Want example Jo understand?

Grunk give cave-speak. Mixed logit: people different. Random taste in model. Simulate many draws to get probs. Works with panel data. Good for real world choices. Want more cave-speak on other chapter?

Grunk read. Discrete choice is study of how people pick one option from many. Models predict choice probs from utility each option gives. Book cover logit, probit, mixed logit, GEV, estimation by simulation, and uses for forecasting.

Grunk read mixed logit chapter. Mixed logit lets taste vary across people. It can approximate any substitution pattern. Grunk summarize: random coefficients, simulate choice probs, use many draws, panel data support.
