Word
log odds
Definition
n. the mathematical logarithm of the odds of an event occurring, used to make probabilities easier to work with.
n. the natural logarithm of the ratio of the probability of an event to the probability of its complement, mapping probabilities from the unit interval to the real line.
Examples
“Logistic regression calculates the log-odds of a student passing the examination.”
“In binary classification, a decision boundary occurs where the log-odds equal zero.”
“Updating linear weights in logistic models adjusts the log-odds additively, simplifying the Bayesian accumulation of evidence.”

Real-World Examples
“When probability is greater than 0.5, odds are greater than 1, and log odds are positive.” “In statistics, a logistic model (or logit model) is a statistical model that models the log-odds of an event as a linear combination of one or more independent variables.” Etymology
Compound statistical term from log (short for logarithm) and odds (from Old Norse odda-madhr, 'odd-man, third man giving casting vote'). Central to logistic regression.
