LOGIT
Binary logistic regression and interactive D3 results.
Syntax
LOGIT(outcome,LIST(X1,X2))Returned object
LogitCombo (D3ComboOperator).
EXTRACT(model,fitted): fitted event probabilities; EXTRACT(model,series): observed outcome.
Example
model=LOGIT(outcome,LIST(X1,X2))
probabilities=EXTRACT(model,fitted)Interpretation and limitations
Binary logit models P(Y=1|X)=1/(1+exp(-Xβ)). Supply a 0/1 dependent variable, align observations, and include an intercept in the design matrix. Coefficients are log-odds effects, not probability-point changes. Accuracy depends on the classification threshold and should not be treated as proof of predictive validity.
