my first analysis with geoRglm was my first ever introduction to geostatistics and spatial modelling...perhaps I am being overambitious! Many thanks in advance, Nicola Batchelor University of Edinburgh and University of Southampton ___ R-sig-Geo mai

[R-sig-Geo] Binom.krige.bayes sim.predict question

2009-07-29 Thread Nicola Batchelor
Dear list, I've been using geoRglm for parameter estimation and spatial predictions for a disease dataset along with 3 predictor variables. I just have a quick question about the option sim.predict in output.glm.control - am I correct in thinking that when this is set to TRUE, you end up with

[R-sig-Geo] Model Based geostatistics and covariance models

2009-04-01 Thread Nicola Batchelor
Dear list, I'm using geoRglm with the log link function and a number of covariates. I'm having convergence and mixing problems with my MCM algorithms and my supervisors and I have come up with a few suggestions for what the problem could be (I'm a novice geostatistician and R-user). I was wond

Hi Ken, I've also been using geoRglm for similar analyses, and found the prediction to be a bit fickle when it comes to the prediction grids! I was having similar problems to yours and the only thing that I could do to make it work was to alter the way I made my prediction grids. How are you c

[R-sig-Geo] autologistic model in R

2009-01-14 Thread Nicola Batchelor
Dear all, I'm currently using a logistic regression model for my dataset, which has a binary outcome of 0 or 1. I've looked at the residuals, which are spatially autocorrelated, so I want to do an autologistic regression model to remove any residual correlation. I've been looking online, a
