They can handle random taste variation, they allow any pattern of substitution, and they are applicable to panel data with temporally correlated errors. The only limitation of probit models is that they require normal distributions for all unobserved components of utility.

The link function for the probit is based on the inverse normal distribution, so: P(y= 1jx) = Z X 1 ˚(z)dz= ( X ); (6) where ( ) and ˚() denote both the normal cumulative and probability density functions respectively. WebbThe Probit model corrects the distortion created in the linear probability model and limits the probability of default between 0 and 1.
