Máximo aprovechamiento de métodos de actualización matricial
There exist a huge number of updating methods for input-output tables, some of them simple and others more complex, depending on their formulation. The information available to enable the application of these methods differs; hence certain methods cannot be used in some models. In practice, the reference figures needed to use non-survey tools are published by statistical offices with certain delay. For this reason, updated tables are available only at a later stage. This paper puts forward, from a global perspective, an adjustment procedure for those cases where information is scarce. Specifically, an explanation is given as to how the RAS method can be applied without needing to know the row and column sums of the relevant matrices.
