scatterplot_fitted_vs_true: Plot Fitted vs. True Dissimilarities

In topolow: Force-Directed Euclidean Embedding of Dissimilarity Data

Plot Fitted vs. True Dissimilarities

Description

Creates diagnostic plots comparing fitted dissimilarities from a model against the true dissimilarities. It generates both a scatter plot with an identity line and prediction intervals, and a residuals plot.

Usage

scatterplot_fitted_vs_true(
  dissimilarity_matrix,
  p_dissimilarity_mat,
  scenario_name,
  ndim,
  save_plot = FALSE,
  output_dir,
  confidence_level = 0.95
)

Arguments

dissimilarity_matrix	Matrix of true dissimilarities.
p_dissimilarity_mat	Matrix of predicted/fitted dissimilarities.
scenario_name	Character string for output file naming. Used if save_plot is TRUE.
ndim	Integer number of dimensions used in the model.
save_plot	Logical. Whether to save plots to files. Default: FALSE.
output_dir	Character. Directory for output files. Required if save_plot is TRUE.
confidence_level	Numeric confidence level for prediction intervals (default: 0.95).

Value

A list containing the scatter_plot and residuals_plot ggplot objects.

Examples

# Create sample data
true_dist <- matrix(runif(100, 1, 10), 10, 10)
pred_dist <- true_dist + rnorm(100)

# Create plots without saving
plots <- scatterplot_fitted_vs_true(
  dissimilarity_matrix = true_dist,
  p_dissimilarity_mat = pred_dist,
  save_plot = FALSE
 )

# You can then display a plot, for instance:
# plots$scatter_plot
