   Sammanfattning : This study delves into the application of Small Area Estimation (SAE) techniques to enhance the accuracy of predicting global needs for assistive spectacles. By leveraging the power of SAE, the research undertakes a comprehensive exploration, employing arange of predictive models including Linear Regression (LR), Empirical Best Linear Unbiased Prediction (EBLUP), hglm (from R package) with Conditional Autoregressive (CAR), and Generalized Linear Mixed Models (GLMM).

3. 2. An Empirical Investigation of the Merits of a Class of Analytically Tractable Matern Covariance Structures in Spatial Data Analysis

   Master-uppsats, Högskolan Dalarna/Mikrodataanalys

   Författare :Ross May; [2017]
   Nyckelord :;

   Sammanfattning : I investigate, using the R package spaMM, the effect of misspecification of the smoothing parameter, Q, of the Matern covariance structure on the mean part of hierarchical generalised linear models (HGLMs) with spatially correlated Gaussian Matern random effects. In particular, by restricting Q to the set {0.5, 1.5, 2. LÄS MER
