WebLogistic regression The linear predictor in logistic regression is theconditional log odds: log P(y = 1jx) P(y = 0jx) = 0x: Thus one way to interpret a logistic regression model is that a one unit increase in x j (the jth covariate) results in a change of j in the conditional log odds. Or, a one unit increase in x j results in a multiplicative ... WebA linear regression with the linearized regression function in the referred-to example is based on the model lnhYii = β 0 +β 1xei +Ei, where the random errors Ei all have the same normal distribution.
