opts_chunk$set(warning=FALSE, message = FALSE, echo = FALSE)Analysis description
Data subset
The rpqa.1 dataset contains only those participants where paternal age is known and the birthdate is between 1630 and 1750.
Model description
All of the following models are the same as our main model m3, except for the noted changes to test robustness.
s1: Mediation via age
Here, we tested whether the effect on reproductive success is mediated by age (mortality). We entered an unknown age for people who did not have a death date on their records and most likely outlived the observation period of the church records.

Estimates are exp(b). When they are referring to the hurdle (hu) component, or a dichotomous outcome, they are odds ratios, when they are referring to a Poisson component, they are hazard ratios. In both cases, they are presented with 95% credibility intervals. To see the effects on the response scale (probability or number of children), consult the marginal effect plots.

Marginal effect plots
In these marginal effect plots, we set all predictors except the one shown on the X axis to their mean and in the case of factors to their reference level. We then plot the estimated association between the X axis predictor and the outcome on the response scale (e.g. probability of survival/marriage or number of children).
plot.brmsMarginalEffects_shades(
x = marginal_effects(model, re_formula = NA, probs = c(0.025,0.975)),
y = marginal_effects(model, re_formula = NA, probs = c(0.1,0.9)),
ask = FALSE)
Coefficient plot
Here, we plotted the 95% posterior densities for the unexponentiated model coefficients (b_). The darkly shaded area represents the 50% credibility interval, the dark line represent the posterior mean estimate.
mcmc_areas(as.matrix(model$fit), regex_pars = "b_[^I]", point_est = "mean", prob = 0.50, prob_outer = 0.95) + ggtitle("Posterior densities with means and 50% intervals") + analysis_theme + theme(axis.text = element_text(size = 12), panel.grid = element_blank()) + xlab("Coefficient size")
Diagnostics
These plots were made to diagnose misfit and nonconvergence.
Posterior predictive checks
In posterior predictive checks, we test whether we can approximately reproduce the real data distribution from our model.
brms::pp_check(model, re_formula = NA, type = "dens_overlay")
brms::pp_check(model, re_formula = NA, type = "hist")
Rhat
Did the 6 chains converge?
stanplot(model, pars = "^b_[^I]", type = 'rhat')
Effective sample size over average sample size
stanplot(model, pars = "^b", type = 'neff_hist')
Trace plots
Trace plots are only shown in the case of nonconvergence.
if(any( summary(model)$fixed[,"Rhat"] > 1.1)) { # only do traceplots if not converged
plot(model, N = 3, ask = FALSE)
}File/cluster script name
This model was stored in the file: coefs/rpqa/s1_control_age.rds.
Click the following link to see the script used to generate this model:
opts_chunk$set(echo = FALSE)
clusterscript = str_replace(basename(model_filename), "\\.rds",".html")
cat("[Cluster script](" , clusterscript, ")", sep = "")s2: Mediation via reproductive timing
Here, we tested whether the paternal age effect on reproductive succes is mediated by reproductive timing (as indexed by anchors’ ages at first and last birth). Because age at first and last birth are by definition only available for anchors who had at least one child, this analysis has to be restricted to such anchors. Hence, paternal age effects on mortality until age 1 and 15 cannot, in principle, be mediated by reproductive timing of the anchors.

Estimates are exp(b). When they are referring to the hurdle (hu) component, or a dichotomous outcome, they are odds ratios, when they are referring to a Poisson component, they are hazard ratios. In both cases, they are presented with 95% credibility intervals. To see the effects on the response scale (probability or number of children), consult the marginal effect plots.

Marginal effect plots
In these marginal effect plots, we set all predictors except the one shown on the X axis to their mean and in the case of factors to their reference level. We then plot the estimated association between the X axis predictor and the outcome on the response scale (e.g. probability of survival/marriage or number of children).
plot.brmsMarginalEffects_shades(
x = marginal_effects(model, re_formula = NA, probs = c(0.025,0.975)),
y = marginal_effects(model, re_formula = NA, probs = c(0.1,0.9)),
ask = FALSE)
Coefficient plot
Here, we plotted the 95% posterior densities for the unexponentiated model coefficients (b_). The darkly shaded area represents the 50% credibility interval, the dark line represent the posterior mean estimate.
mcmc_areas(as.matrix(model$fit), regex_pars = "b_[^I]", point_est = "mean", prob = 0.50, prob_outer = 0.95) + ggtitle("Posterior densities with means and 50% intervals") + analysis_theme + theme(axis.text = element_text(size = 12), panel.grid = element_blank()) + xlab("Coefficient size")
Diagnostics
These plots were made to diagnose misfit and nonconvergence.
Posterior predictive checks
In posterior predictive checks, we test whether we can approximately reproduce the real data distribution from our model.
brms::pp_check(model, re_formula = NA, type = "dens_overlay")
brms::pp_check(model, re_formula = NA, type = "hist")
Rhat
Did the 6 chains converge?
stanplot(model, pars = "^b_[^I]", type = 'rhat')
Effective sample size over average sample size
stanplot(model, pars = "^b", type = 'neff_hist')
Trace plots
Trace plots are only shown in the case of nonconvergence.
if(any( summary(model)$fixed[,"Rhat"] > 1.1)) { # only do traceplots if not converged
plot(model, N = 3, ask = FALSE)
