Hi R-helpers, I have a character object called dd that has 32 elements each of which is a model formula contained within quotation marks. Here's what it looks like: > dd [1] "lm(y ~ 1,data=Cement)" "lm(y ~ X,data=Cement)" "lm(y ~ X1,data=Cement)" [4] "lm(y ~ X2,data=Cement)" "lm(y ~ X3,data=Cement)" "lm(y ~ X4,data=Cement)" [7] "lm(y ~ X + X1,data=Cemen...

Using the Cement hardening data in Anderson (2008) Model Based Inference in the Life Sciences. A Primer on Evidence, and working with the best model which is lm ( y ~ x1 + x2, data = cement ) the AIC value from R is model <- lm ( formula = y ~ x1 + x2 , data = cement )...

...that dredge is able to separate individual smooth terms out of say s(a,b). Hence an additional request, if anyone has example code for using gam in a multimodel inference framework, especially with bivariate smooths, I'd be most grateful. Cheers and Thanks in Advance Mike require(MuMIn) data(Cement) # option 1, create model.selection object using dredge fm0 <- lm(y ~ ., data = Cement) print(dd <- dredge(fm0)) fm1 <- lm(formula = y ~ X1 + X2, data = Cement) fm2 <- lm(formula = y ~ X1 + X2 + X4, data = Cement) fm3 <- lm(formula = y ~ X1 + X2 + X3, data = Cement) fm4 <- lm(form...

Hi All: the package "MuMIn" can be used to select the model based on AIC or AICc. The code is as follows: data(Cement) lm1 <- lm(y ~ ., data = Cement) dd <- dredge(lm1,rank="AIC") print(dd) If I want to select the model by BIC, what code do I need to use? And when to select the best model based on AIC, what the differences between the function "dredge" in package"MuMIn" and th...

I just r-sync'ed the r-devel version of R-1.7.0 (2003-03-11), compiled it under RH-8.0 and ran make check. The reg-tests-2 fails at the very end with the message stating that "object cement was not found". It looks like this piece of the regression test is new to version 1.7. The the piece of code generating the error is: if(require(MASS)) { teststep <- function(formula, data) { d2 <- data fit <- lm(formula, data=d2) step(fit) }...

Hello, I'd like to sum the weights of each independent variable across linear models that have been evaluated using AIC. For example: > library(MuMIn) > data(Cement) > lm1 <- lm(y ~ ., data = Cement) > dd <- dredge(lm1, beta = TRUE, eval = TRUE, rank = "AICc") > get.models(dd, subset = delta <4) There are 5 models with a Delta AIC Score of less than 4. I would like to sum the weights for each of the independent va...

...advise if it is possible to show models with any two only certain variables. Thank you. Elaine I asked a similar question and got a great help for models with only one variable as below. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ In effect, you want data(Cement) lm1 <- lm(y ~ ., data = Cement) dd <- dredge(lm1, subset = X1) want <- with(dd, is.na(X) & is.na(X2) & is.na(X3) & is.na(X4)) want ## how many models selected? sum(want) ## OK selected just 1, show it dd[want, , drop = FALSE] Oh, actually, I suppose you could automate this,...

Hello, I am using package MuMIn to calculate AIC for a full model with 10 explanatory variables. Thanks in advance in sharing your experience. Q1 In the AIC list of all models, each model is differentiated by model number. Please kindly advise if it is possible to find the corresponding explanatory variable(s) for the model number. Q2 error message I tried to display sub-model with only

Hi, Ive been trying to work out how to get wbinfo to list members of a specific AD group, rather than list groups a specific user is in. So far I have had no luck... In fact im not sure its possible with wbinfo. Is there another tool which could do this? James -- Sent using Dekko from my Ubuntu device

Hi All: Recently I am researching my dissertation about the quantile model selection by bayesian approach. I have the dependent variable(return) and 16 independent variables and I need to select the best variable for each quantile of return. And the method I used is the bayesian approach, which is based on calculating the posterior distibution of model identifier. In other words, I need to obtain
