Here, a clear trend in the data can be observed, with more values observed close to the bottom left corner. The first model we fit to the SPDEtoy dataset with INLA is a linear regression on the coordinates. This will be done using function inla(), which takes similar arguments to …

WebbDataset: Leukemia in upstate New York. To illustrate how spatial models are fitted with INLA, the New York leukemia dataset will be used.This has been widely analyzed in the literature (see, for example, Waller and Gotway, 2004) and it is available in the DClusterm package. The dataset records a number of cases of leukemia in upstate New York at … WebbIn the simulations INLA is systematically compared with the popular method of Maximum Likelihood via Laplace Approximation. By an application to the classical salamander mating data, we compare INLA with the best performing methods. Given the computational speed and the generally good performance, INLA tim rose albums

Furthermore, this method can return the uncertainties of the prediction. tim rosland

"Webb15 juli 2024 · The INLA methodology is developed for approximate Bayesian inference of latent Gaussian models (LGMs). Most statistical models, including survival models with interval censoring are indeed LGMs, although not at first sight. In Sect. 3 we show how a survival model with interval censoring can be defined as an LGM. " - Inla statistics

It works in a very similar way to the glm () function and, in its simplest form, it will take a formula with the model to fit and the data. It returns an object of class inla with all the results from model fitting.
