Pdemesh (model) plots the mesh contained in a 2-D or 3-D model object of type PDEModel.

PP Plots

The PP plot for comparing a sample to a theoretical model plots the theoretical proportion less than or equal to each observed value against the actual proportion.

For a theoretical cumulative distribution function (F) this means plotting

[F(x_{(i)}) sim p_i]

For the fheight variable in the father.son data:

  • The values on the vertical axis are the probability integral transform of the data for the theoretical distribution.

  • If the data are a sample from the theoretical distribution then these transforms would be uniformly distributed on ([0, 1]).

  • The PP plot is a QQ plot of these transformed values against a uniform distribution.

  • The PP plot goes through the points ((0, 0)) and ((1, 1)) and so is much less variable in the tails:

Adding the data:

The PP plot is also less sensitive to deviations in the tails.

A compromise between the QQ and PP plots uses the arcsine square root variance-stabilizing transformation, which makes the variability approximately constant across the range of the plot:

Adding the data:

Type of plot. There are three groups of plot-types:
Coefficients (related vignette)

type = 'est'

Forest-plot of estimates. If the fitted model only contains one predictor, slope-line is plotted.

type = 're'

For mixed effects models, plots the random effects.

type = 'std'

Forest-plot of standardized beta values.

type = 'std2'

Forest-plot of standardized beta values, however, standardization is done by dividing by two sd (see 'Details').

Marginal Effects (related vignette)

type = 'pred'

Predicted values (marginal effects) for specific model terms. See ggpredict for details.

type = 'eff'

Similar to type = 'pred', however, discrete predictors are held constant at their proportions (not reference level). See ggeffect for details.

type = 'int'

Marginal effects of interaction terms in model.

Model diagnostics

Plots Modeler Vs

type = 'slope'
Plots modeler using

Slope of coefficients for each single predictor, against the response (linear relationship between each model term and response).

type = 'resid'

Slope of coefficients for each single predictor, against the residuals (linear relationship between each model term and residuals).

Plots Modeler Software

type = 'diag'

Check model assumptions.

Note: For mixed models, the diagnostic plots like linear relationship or check for Homoscedasticity, do not take the uncertainty of random effects into account, but is only based on the fixed effects part of the model.
