Where censored approaches to LGD modelling are concerned, Tobit regressions have been suggested as one of the methods to be used for modelling the restricted range of the LGD distribution (Bellotti & Crook, 2012). In a Tobit regression, the observed range of the response variable has a Gaussian...
b)Use Eq.(5)to determine the overall error. There are 3 steps to solve this one. Explanation: Linear least -squares regression is a statistical method that uses a line of best to find a line fro...
