Legacy Materials

This page keeps the older long-form documents visible without requiring the live website to preserve their original structure or style.

The basic rule is:

• the newer website pages are the preferred first stop,
• the older PDFs remain valuable as archival references,
• changelog material should live in one canonical place, not be duplicated in FAQ documents.

Legacy package material

np

• Current CRAN vignettes: np vignette index
• Current getting-started vignette: np_getting_started
• Current entropy vignette: np_entropy_tests
• Historical names such as np.pdf, entropy_np.pdf, and np_faq.pdf refer to older PDF-era materials and are no longer hosted in the current CRAN vignette set.

crs

• Current CRAN vignettes: crs vignette index
• Current getting-started vignette: crs_getting_started
• Historical names such as crs.pdf, spline_primer.pdf, and crs_faq.pdf refer to older PDF-era materials and are no longer hosted in the current CRAN vignette set.

Current website-first replacements

For np

• Kernel Primer
• Density, Distribution, Quantiles
• Semiparametric Models
• Entropy and Testing
• Classification and Modes
• Significance and Specification
• Build With npksum
• Plotting and Intervals

For crs

• Splines
• Spline Primer

For npRmpi

• MPI and Large Data

Why keep the older documents at all?

Because they still contain useful exposition, examples, and historical context, even when the presentation style is now dated. The aim of the redesign is not to erase that material. It is to give users a clearer first route through it.

What is not being carried forward

The old FAQ habit of manually reproducing changelog material is not being preserved. Current change tracking should live in package release notes and NEWS.md, not in multiple hand-maintained PDFs.
