associated S3 methods have been updated accordingly (e.g.,
summary.brs, plot.brs).type argument removed: The
deprecated type argument has been completely removed from
all functions: check_response(),
prepare_data(), betaregscale(),
betaregscale_fit(), betaregscale_fit_z(),
betaregscale_loglik(),
betaregscale_loglik_z(),
betaregscale_simulate(),
betaregscale_simulate_z(), and internal helpers
compute_start(), .extract_response(),
.build_simulated_response(), and
.compute_endpoints(). The midpoint interval geometry
(type = "m") is now the only option and is hardcoded
internally. Users who previously relied on type = "l" or
type = "r" should use prepare_data() to supply
custom left/right endpoints instead.
Renamed bs_prepare() to
prepare_data(): The data preparation function has
been renamed to prepare_data() to be more descriptive and
consistent with the package’s verb-based API. The returned data frame
now carries the is_prepared attribute instead of
bs_prepared.
delta argument in simulation
functions: betaregscale_simulate() and
betaregscale_simulate_z() gain a delta
argument (default NULL) that forces all simulated
observations to a specific censoring type: 0 (exact), 1 (left), 2
(right), or 3 (interval). This enables targeted Monte Carlo studies
where the analyst controls the censoring structure.
When delta is non-NULL, the actual simulated values
(y_raw = rbeta(n, a, b)) are preserved on the scale grid,
and the forced censoring indicator is passed to
check_response() as a vector. This ensures that each
observation retains its covariate-driven variation with
observation-specific endpoints.
The returned data frame carries
attr(, "bs_prepared") = TRUE so that
betaregscale(), betaregscale_loglik(), and all
fitting functions use the pre-computed left,
right, yt, and delta columns
directly, bypassing the automatic boundary classification. Without this
attribute, the fitting pipeline would re-classify the response from the
y column alone, which would ignore the forced
delta.
delta argument in
check_response(): accepts an integer vector of
pre-specified censoring indicators, overriding the automatic
boundary-based classification on a per-observation basis. The endpoint
formulas adapt to non-boundary observations:
| delta | condition | left (l_i) | right (u_i) |
|---|---|---|---|
| 0 | any | y / K | y / K |
| 1 | y = 0 | eps | lim / K |
| 1 | y != 0 | eps | (y + lim) / K |
| 2 | y = K | (K - lim) / K | 1 - eps |
| 2 | y != K | (y - lim) / K | 1 - eps |
| 3 | type “m” | (y - lim) / K | (y + lim) / K |
The distinction between boundary and non-boundary observations is essential: when delta = 1 is forced on a non-zero y, the upper bound uses the actual y value ((y + lim)/K) rather than the fixed boundary formula (lim/K). This preserves the information content of each observation.
Observation-specific endpoints in
bs_prepare(): the internal
.compute_endpoints() helper now uses the same adaptive
formulas as check_response() for analyst-forced left/right
censoring on non-boundary scores. Previously, delta = 1 always produced
right = lim/K and delta = 2 always produced
left = (K - lim)/K, regardless of the actual y
value.
Simulation with forced delta = 1 or
delta = 2: the internal
.build_simulated_response() helper previously replaced all
y values with boundary values (y_grid = rep(0, n) for delta
= 1, y_grid = rep(ncuts, n) for delta = 2). This produced
degenerate data where every observation had identical endpoints (e.g.,
all left = 0.995, right = 0.99999 for delta = 2),
destroying all covariate-driven variation and making regression fitting
impossible.
The fix preserves the actual simulated grid values
(y_grid = round(y_raw * ncuts)) and passes a forced delta
vector to check_response(), which computes
observation-specific endpoints using the actual y values.
Missing "bs_prepared" attribute on
simulation output: when delta was forced, the
simulation functions did not mark the output with
attr(, "bs_prepared") = TRUE. As a result,
betaregscale() would re-classify the response via
check_response(), silently overwriting the forced delta
with automatic boundary rules. The attribute is now set
correctly.
type parameter ("m", "l",
"r") is deprecated across all functions:
betaregscale(), betaregscale_fit(),
betaregscale_fit_z(), betaregscale_loglik(),
betaregscale_loglik_z(),
betaregscale_simulate(),
betaregscale_simulate_z(), check_response(),
and prepare_data(). Use prepare_data() to
control interval geometry instead. The parameter still works but emits a
deprecation warning when passed explicitly.bs_prepare() data preprocessing: new
analyst-facing function that validates, classifies censoring, and
rescales raw data before model fitting. Supports four flexible input
modes: score-only, score + explicit delta, interval endpoints with NA
patterns, and analyst-supplied left/right bounds. Prepared data is
automatically detected by betaregscale()..extract_response() enables transparent
detection of bs_prepare()-processed data across all
fitting, log-likelihood, and starting-value functions.censoring_summary() now also accepts data frames from
bs_prepare().bs_prepare()
receives a subset data frame with non-sequential row names. Output now
always has sequential row names (1:n).bbmle. All model fitting now uses
stats::optim() directly with analytical gradients via the
