mixed effects mle2 model r

I need to fit a ricker model to my data that has random effects for each area and then plot the output. I used the answer from How do I plot a mle2 fit of a model in ggplot2, along with the data? to write my own model:

dat_HG_Ricker=data[,c("EST.1.100m","Redds.100m","Clean")]

rickerfun <- function(x,a,b) {
    a*x*exp(-b*x)
}

m1 <- mle2(EST.1.100m ~ dlnorm(meanlog=log(rickerfun(Redds.100m,a,b)),
                         sdlog=exp(logsdlog)),
       method="L-BFGS-B",
       lower=c(a=1e-2,b=1e-2,logsdlog=-10),
       start=list(a=55.80234,b=0.8058173,logsdlog=0),
       data=dat_HG_Ricker)


slnorm <- function(meanlog, sdlog) {
   list(title="Log-normal",
        median=exp(meanlog),
        mean=exp(meanlog+sdlog^2/2))
}

m2 <- lm(log(EST.1.100m) ~ Redds.100m+ offset(log(Redds.100m)),
          data=dat_HG_Ricker)

m3 <- glm(EST.1.100m ~ Redds.100m+ offset(log(Redds.100m)),
      data=dat_HG_Ricker,
      family=Gamma(link="log"))

m4 <- nls(EST.1.100m ~ a*Redds.100m*exp(-b*Redds.100m),
      start=rsv,
      data=dat_HG_Ricker)


predframe <- data.frame(Redds.100m=seq(0,5.5,length=51))
predframe$mle2 <- predict(m1,newdata=predframe)
predframe$mle_med <- predict(m1,newdata=predframe,location="median")
predframe$loglm <- exp(predict(m2,newdata=predframe))
predframe$glm <- predict(m3,newdata=predframe,type="response")
predframe$nls <- predict(m4,newdata=predframe)


predframe_m <- reshape2::melt(predframe,id.var="Redds.100m",
                              variable.name="model",
                              value.name="EST.1.100m")

library(ggplot2)
ggplot(dat_HG_Ricker,aes(Redds.100m,EST.1.100m))+ geom_point() +
    geom_smooth(method="glm",
                formula=y~x + offset(log(x)),
                method.args=list(family=Gamma(link="log")))+
    geom_point(data=predframe_m,aes(colour=model,shape=model))

In the code

rsv
$a
[1] 55.80234

$b
[1] 0.8058173

So, the random effect to the model would be for the variable "Clean". I am not married to using mle2(). Ideally, I would like a plot that looks something like this, with each area ("Clean") having its own line to show fit, and additionally a model mean line:

It is unfortunately still the case that I am aware of no easy, off-the-shelf, deterministic/frequentist way to fit arbitrary generalized nonlinear mixed models in R. You don't appear to need a generalized NLMM (i.e., you're happy with a log-Normal response, which can be model with a log-transformed Gaussian response). (If you did, your choices seem to be (1) brms (not deterministic/frequentist); (2) TMB (not off-the-shelf), (3) JAGS/Nimble/Greta (neither deterministic/frequentist nor off-the-shelf) ...)

You could use a nonlinear mixed model: nlme() would work (lme4::nlmer() would theoretically work, but is finickier). However, you can get away with a LMM, which is easier — as I said in the comments,

... use the "log-Ricker" trick, i.e. fit the model as log(y) ~ x + offset(log(x)) in the linear mixed model engine of your choice (log(y) = a + log(x) + b*x → y = exp(a)*x*exp(b*x))

For these data, I ended up assuming the random intercepts and slopes were uncorrelated (i.e., using ||) because otherwise I got a singular fit (correlation = -1); ideally your full data set is larger and you don't have to do this ...

library(lme4)
m1 <- lmer(log(EST.1.100m) ~ offset(log(Redds.100m)) + Redds.100m +
         (1 + Redds.100m || Clean),
     dat_HG_Ricker)

Construct prediction frames, one group-specific and one general (by hand: you could also use emmeans or ggeffects or ...)

pframe <- with(dat_HG_Ricker,
               expand.grid(Clean = factor(unique(Clean)),
                           Redds.100m = seq(0, 5, length = 51)))
pframe0 <- unique(pframe["Redds.100m"])
pframe$EST.1.100m <- exp(predict(m1, newdata = pframe))
pframe0$EST.1.100m <- exp(predict(m1,    newdata = pframe0, re.form = NA))

Plot:

library(ggplot2); theme_set(theme_bw())
ggplot(dat_HG_Ricker, aes(Redds.100m, EST.1.100m, colour = Clean)) +
    geom_point() +
    geom_line(data=pframe) +
    geom_line(data=pframe0, colour = "black", lwd = 2)

For graphical purposes, you might want to indicate some more about where the data for each group actually lie. You could:

• use ggalt::geom_encircle(aes(fill = Clean), colour = NA, alpha = 0.08) to colour in regions
• restrict each population-level prediction curve to the x-range actually covered for that group (perhaps extending the curve with a dashed line, although that gets pretty fussy ...)
