lambdastar 0.8.1
- Correct README links to files included in the source package and
remove the private audit reference.
- Exclude internal audit, validation and delivery reports and result
tables from the CRAN archive. Retain user guides, runnable examples and
package tests.
- Remove documentation references to excluded reports. Statistical
calculations and percentile semantics are unchanged.
lambdastar 0.8.0
- Add lambda_panel() for fixed person-by-occasion models with parallel
indicators, explicit observation maps, conditional term blocks and
person-level case selection.
- Implement default person-intercept adjustment by group demeaning;
reuse the existing hypothesis, temperature and numerical F_H
evaluator.
- Bootstrap whole persons with distinct copy identities, rebuilding
person-specific columns and degrees of freedom while preserving declared
non-person encoding.
- Deliver the derivation, an executable panel lesson and independent
numerical, resampling, fixed-profile and compatibility evidence.
- Enforce the exact saturation identity for captured energy. If
boot::boot.ci returns no percentile endpoints, report
quantile_unavailable without a crash or substituted limits. Ordinary
percentile semantics remain unchanged.
lambdastar 0.7.0
- Add lambda_reference() for a known scalar/vector origin and explicit
retained mean direction, through the existing design, projection and F_H
evaluator. Use d=N without nuisance, literal nuisance columns and
uncentered encoded volume.
- Add lambda_paired() for matching after-minus-before parallel
measurement pairs. Estimate temperature from the differences and require
T_q on their mean scale.
- Carry known reference values with case/stratum/cluster draws;
require a common origin/reference recipe for comparisons. Retain
ordinary percentile semantics, zero/singular diagnostics and the
existing centered/population behavior.
- Include the derivation, a default-bootstrap lesson, independent
fixed-profile and paired-covariance checks, plus regression evidence for
the centered API.
lambdastar 0.6.1
- Complete the centered model-space learning path with an explicit
supported-scope table, conditional-reference interpretation, coding
comparisons and finite-N population-target examples.
- Include the E4 distribution/resource report, compact evidence and
two synthetic datasets with a runnable ordinary-percentile lesson for
regular and weak signal.
- Make the model-space lessons reproducible under caller RNG and
contrast options; regenerate help and deliver a checked source archive.
Numerical algorithms, estimator selection, bootstrap defaults and
endpoint rules are unchanged.
lambdastar 0.6.0
- Add lambda_contrast() for named homogeneous coefficient restrictions
L beta=0, using stable coefficient-space solves and the explicit
restricted null model.
- Add lambda_marginal_contrast() for predictor settings and signed
averaging weights, with learned polynomial, spline and scale prediction
coordinates.
- Add encoding=“fixed” to design constructors; retain reevaluation as
the default. Freeze raw encodings only after common selection, and
rebuild full/null geometry in every case or cluster draw. Preserve
declared L coding for F_H.
- Allow comparisons of invertible contrast recodings with a common
null reference. Diagnose unidentified full models, redundant
restrictions and unsupported grid recipes. Keep percentile intervals,
estimators and invalid-draw rules unchanged.
- Include a runnable contrasts/bases lesson and independent
restricted-fit, compatibility, resampling and portable-replay
validation.
lambdastar 0.5.0
- Add lambda_design() for portable, row-bound formula/lm/matrix
specifications and lambda_hypothesis() for target terms conditional on
explicit adjustment.
- Preserve declared coding, factor contrasts, common case selection
and existing bootstrap transformation policies. Reject stale inputs and
incompatible model comparison reference recipes. Report conditional
targets and omitted terms.
- Reuse the measurement nuisance state and projected residual energy
for F_H; share thermal calculations within comparisons. Keep the
projection algorithms, estimators, percentile endpoints and
undefined-draw rules unchanged.
- Clarify that homogeneous isotropic measurement fluctuation does not
require Gaussian responses or equal total group variances. The
population estimator retains its separate assumptions. General
coefficient restrictions and new reference/paired-mean spaces remain
later increments.
lambdastar 0.4.1
- Add an executable seven-chapter teaching example with known
simulated signal, plots, prediction checkpoints, inspectable bootstrap
draws and editable noise, item-count, sample-size and coding
experiments. Preserve the compact quickstart.
- Add separate population, nuisance, school-cluster and zero-case
examples. Teaching runs preserve RNG state and save results only to a
new/empty folder.
- Include a worked default run and its figures in the installed
documentation. Statistical estimators and numerical algorithms are
unchanged from 0.4.0.
lambdastar 0.4.0
- License the package under Apache 2.0 and use
mike.hammes@mikehammes.name as the author and maintainer contact.
- Make
estimator="paper" the default throughout points,
returned lambda/kappa fields, summaries and bootstrap draws. Keep
estimator="population" explicit; estimates and
inference identify the selected calculation. This changes
the default bootstrap statistic from 0.3.1; choose population to retain
that method.
- Add shared nuisance formula/matrix adjustment to measurement, model
and comparison APIs, using N-rank(B) and refitting nuisance effects on
every draw.
- Add whole-cluster resampling within strata, variable draw sizes and
optional row-index lists. Add explicit type-7 percentile interpolation
for paper replay.
- Retain ordinary percentile intervals, reduced contrast coding,
undefined-value diagnostics and caller RNG restoration. No CI endpoint
alterations.
- Add independent conditional-moment, cluster and estimator checks,
plus public API reproduction of the OECD manuscript analysis and
random-design validation.
lambdastar 0.3.1
- Preserve explicit factor contrast matrices, including fewer than G-1
columns, when rebuilding bootstrap models. Formula transformations,
saved lm models and comparisons use the supplied coding without adding
contrast directions.
- Add regression tests against explicit design matrices and
independent OLS for reduced contrasts, transformations and
interactions.
lambdastar 0.3.0
- All bootstrap confidence intervals use direct percentiles of the
parameter draws, computed by boot::boot.ci(type=“perc”). Defaults:
B=5000, 95%, seed=1.
- Population point estimation is independent of confidence intervals
and is available also with bootstrap=FALSE. The same estimator runs on
every draw.
- Undefined kappa, singular temperature and model failures are counted
explicitly. Missing draws suppress the affected regular interval; valid
zero and one values stay in their distributions.
- Optional conditional_quantiles are a separate descriptive output.
They never substitute for a regular interval.
- ci.method accepts only “percentile”, also for temperature
intervals.
- Existing finite-person numerical estimates and F_H calculations are
preserved.
lambdastar 0.1.0
- Locally installable measurement core, model adapters, numerical F_H
and common-data comparison wrapper, with executable examples and
validation.
lambdastar 0.0.3
- Person-bootstrap infrastructure, RNG restoration and
diagnostics.
lambdastar 0.0.2
- Model adapters, common-case comparison and S3 summaries.
lambdastar 0.0.1
- Measurement/projection core, numerical capacity, temperature
integrals, encoded geometry and parsimony functional.
