In this paper age-space-time models based on one and two-dimensional P-splines with

In this paper age-space-time models based on one and two-dimensional P-splines with
B-spline bases are proposed for smoothing mortality rates, where both xed relative scale
and scale invariant two-dimensional penalties are examined. Model tting and inference
are carried out using integrated nested Laplace approximations (INLA), a recent Bayesian
technique that speeds up computations compared to McMC methods. The models will be
illustrated with Spanish breast cancer mortality data during the period 1985-2010, where a
general decline in breast cancer mortality has been observed in Spanish provinces in the last
decades. The results reveal that mortality rates for the oldest age groups do not decrease in
all provinces. [--]
