Code for a mixed effects model: shep <- function(x, a, b, c) { y_pred <- a * x / (1 + (b * x)^c) return(y_pred) } fitme <- lmer(y ~ shep(x, a, b, c) + (1 | Group), data = dat) I would like to fit the equation above using a mixed effects model, with...
mixed-effects modelsmultilevel modelsstructural equation modelsSeveral variants of the autoregressive structural equation model were suggested over the past years, including, for example, the random intercept autoregressive panel model, the latent curve model with structured residuals, and the STARTS model....
To test whether radial variation of wood specific gravity (WSG) is controlled by tree age or tree size in teak (Tectona grandis L.f) plantation trees, opposing different-length pith-to-bark strips which represents the differential lateral growth rate was compared using mixed-effects model which ...
linear mixed-effects models and structural equation models. Both classes of models allow analyzing quantitative longitudinal data and explicitly define parameters related to both stability and change processes. The models also allow studying interactions between individual and contextual characteristics, both ...
Describe the bug Reporting a bug in linear mixed-effects model. In scenarios where mean is conditional on two grouping variables the estimated coefficients are very far away from the correct ones and the values estimated from same models...
