Probit and logit regression

WebbThere are many intersections around S a = 0. 1, although Probit-1 provides a reasonable overall fit to the fragility curve.The Probit-2-generated fragility curves do not reflect this circumstance. As mentioned in Section 2, although Probit-2 prevents curve intersections, the parameter ζ, which forces the four fragility curves to be the same, has an effect on … http://www.columbia.edu/~so33/SusDev/Lecture_9.pdf

Why Is Logistic Regression the Spokesperson of Binomial Regression …

WebbThe inverse function Φ-1(p) = NORM.S.INV (p) is called the probit function (probit = probability unit) and plays a role similar to the logit function in probit regression. We will also use the notation for the standard normal pdf, φ(z) = NORM.S.DIST (z, FALSE). The probit regression model takes the form Φ-1(p) = β0 + β1x1 + β2x2 + … + βkxk + ε WebbAs maximum likelihood estimates are normally distributed in large samples, statistical inference for coefficients in nonlinear models like Logit and Probit regression can be made using the same tools that are used for linear regression models: we can compute t t -statistics and confidence intervals.
