SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Reusable, battle-tested R modeling patterns that let teams build advanced model-helper layers (specification, formula/builders, data-slicing, fit wrappers, diagnostics, and post-estimation adapters) in a consistent, testable way across Bayesian, causal-design, meta-analysis, lavaan SEM, and tidymodels workflows.

Core Features & Use Cases

  • Modular spec and formula builders that separate estimand, covariates, and random effects for reliable modeling across diverse families (brms, lavaan, metafor, marginaleffects, and tidymodels).
  • Explicit data-materialization boundaries that collect only model-ready frames from large datasets or Arrow Parquet sources, with a clear path from specification to final reporting.
  • A layered architecture that keeps fit, diagnostics, post-estimation, and deployment adapters as independent surfaces, enabling robust testing and reusable components.

Quick Start

Define a modeling spec, build the right-hand side from validated terms, prepare a ready-to-fit data frame, fit the model with data =, and surface tidy post-estimation outputs.

FAQPage Schema
How do I structure reusable R model-building patterns for Bayesian and SEM workflows?

Reusable R model-building patterns separate estimand, covariates, and random effects into modular spec and formula builders, ensuring reliable modeling across Bayesian, lavaan SEM, and tidymodels workflows with explicit boundaries between design, fit, and reporting surfaces.

What is the best way to manage data-materialization boundaries when fitting brms or lavaan models?

Managing data-materialization boundaries involves collecting only model-ready frames from large datasets or Arrow Parquet sources, passing them explicitly via data = to fit wrappers, which keeps the path from specification to final reporting clear and efficient.

Can I use tidymodels and metafor together within a single layered R modeling architecture?

Yes, you can use tidymodels and metafor together within a layered R modeling architecture that maintains fit, diagnostics, post-estimation, and deployment adapters as independent surfaces, enabling robust testing and reusable components across meta-analysis and tidymodels workflows.

How do I build modular formula builders that separate random effects for causal-design models in R?

Modular formula builders separate estimands, covariates, and random effects for causal-design models in R by enforcing a multi-layer contract with explicit boundaries, allowing reliable specification across diverse families like brms and marginaleffects.

Does this R modeling approach support post-estimation summaries and deployment-ready adapters?

Yes, this R modeling approach supports post-estimation summaries and deployment-ready adapters by keeping fit, diagnostics, and reporting as independent surfaces, enabling robust testing and reusable components across Bayesian, SEM, and meta-analytic contexts.
