I have a linear mixed effects model and I am trying to do variable selection. The model is testing the level of forest degradation in 1000 sampled poi ...
I use the iris dataset in R as the example below. The random intercept and slope are shown below. That means the intercept is -0.49549054 (fixed ...
So as the title suggests I would like to visualise these two models that I have in order to better understand their relationship. The first one is a f ...
I want to create a variable with the number of the day a participant took a survey (first day, second day, thirds day, etc.) The issue is that there a ...
I am using glmmTMB to run a zero-inflated two-component hurdle model to determine how certain covariates might influence (1) whether or not a fish has ...
Unfortunately, I had convergence (and singularity) issues when calculating my GLMM analysis models in R. When I tried it in SPSS, I got no such warnin ...
I'm trying to run a multinomial logistic regression with mixed effects. Let's say I have the following variables: Participant (ten participants, each ...
I'd like to build a nonlinear mixed effect model that describes the relationship between two variables, "x" and "y", which vary randomly by a third va ...
I know that I could use lm(a ~ (b + c + d)^2) in order to get all possible two-way interactions in a model, but I need only the interactions with a si ...
I have a number of linear mixed models, which I have fitted with the lmerTest library, so that the summary() of the function would provide me with p-v ...
I am trying to export a table with the results of a mixed ANOVA that I ran with lme4. This is the model. I want to export the ANOVA statistics plus re ...
I am not familiar with nonlinear regression and would appreciate some help with running an exponential decay model in R. Please see the graph for how ...
Hello stackoverflow community! I am new to mixed-effects modelling (MEM) or mixed-models. In order to gain a better understanding of MEM, I decided to ...
I am trying to determine whether there is a significant effect of treatment on microbiome diversity between two timepoints (two timepoints x three tre ...
I have a mixed model where I'm trying to find the significance of my random effect. The model is a mixed model with zero-inflated beta distribution wh ...
I'm trying to fit huge datasets using julia from R. I originally tried jglmm (https://github.com/mikabr/jglmm), but the resulting objects are difficul ...
I have an assignment in mixed effect models, but there is little to none information regarding the "lmer" output. The data used in the assignment rega ...
I am looking for support using SPSS version 28, specifically regarding how to build a custom model using GLM Repeated Measures. I am trying to run a m ...
I'm dealing with problems of three parts that I can solve separately, but now I need to solve them together: extremely skewed, over-dispersed depe ...
