While having been widely accepted and adopted, the model has some limitations that hinder its performance. Some variants of the model have been proposed to deal with these drawbacks individually, none coped with them all at the same time. In …

Without applying SVD or some other method of dimension reduction the table of mortality data is a highly correlated multivariate data series, and the complexity of these multidimensional time series makes them difficult to forecast. SVD has become widely used as a method of dimension reduction in many different fields, including by Google in their page rank algorithm. The Lee–Carter model was introduced by Ronald D. Lee and Lawrence Carter in 1992 with the …
Nettetas a stochastic process, we adopt the approach proposed by Lee and Carter (1992), to model the population health changes. In this way, its stochastic feature is captured by a single latent time index in the first place.
