Inverse Logit Transformation
The inverse logit transformation converts parameter estimates from Logit Models into probabilities.
Where is the fitted value from a Binary Logit Model, the probability is computed as:
Where is the utility for the th of alternatives, the probability of choosing the th alternative is:
For example, if in a MaxDiff experiment analyzed using a logit model the three alternatives, A, B and C, estimated parameters of 0, 0.5 and 0.9, the probability of choosing the first alternative is . And, the probability of choosing B if only B and C were available is:
