melt 1.9.0

CRAN release: 2022-11-04

NEW FEATURES

  • confint() is applicable to an EMLT object to produce simultaneous confidence intervals.

  • All model objects gain control slot of ControlEL class. All methods that apply to these objects inherit control unless it is overwritten by the user explicitly.

MINOR IMPROVEMENTS

  • summary() is applicable to an object that inherits from EL, ELT, and EMLT.

  • A more informative message is printed regarding the convergence status.

  • optim slot in all model or summary objects gains a single logical element cstr that shows whether a constrained EL computation is involved or not.

BUG FIXES

  • confreg() checks whether parm matches the parameters in object when a character vector is specified for parm.

melt 1.8.0

CRAN release: 2022-09-21

NEW FEATURES

  • New accessor method logProb() extracts a model’s log probabilities of empirical likelihood.

  • el_lm() and el_glm() gain an argument offset.

  • el_glm() accepts quasipoisson family with "identity" link function for the argument family.

  • elt() accepts a character vector for the argument lhs, allowing a symbolic description of a hypothesis.

  • eltmt() accepts a character vector as an element of the argument lhs, allowing a symbolic description of hypotheses.

  • plot() applies to an object that inherits from EL to plot empirical likelihood displacement values versus observation index.

  • New dataset thiamethoxam added.

MINOR IMPROVEMENTS

  • coef() and getDF() is applicable to an object of class EMLT.

  • print() shows the tested hypothesis when applied to an object of class ELT.

  • print() shows the tested hypotheses, the estimates, and marginal degrees of freedom when applied to an object of class ELMT. The description of the hypotheses and the estimates are printed only when the marginal degrees of freedom are all one.

  • "boot" option in the calibrate argument of elt() yields a more reliable result when applied to an object that inherits from LM.

  • Internal routines for projection operation do not compute an explicit inverse (thanks to @awstringer1).

BUG FIXES

  • elmt() returns a correct critical value when applied to an object of class QGLM.

  • "boot" option in the calibrate argument of elt() works with an object of class SD.

melt 1.7.0

CRAN release: 2022-08-12

NEW FEATURES

MINOR IMPROVEMENTS

  • print() shows class-specific information.

BUG FIXES

melt 1.6.0

CRAN release: 2022-07-10

BREAKING CHANGES

  • el_mean() takes arguments in a different order to comply with the ‘tidyverse’ style. It takes the data argument x first, followed by the parameter specification par as el_mean(x, par).

  • lht() is renamed to elt().

  • model argument in el_mean(), el_lm(), and el_glm() are removed. Use keep_data in el_control().

NEW FEATURES

  • New package dependencies are added (BH, dqrng, and graphics).

  • New elt() replaces lht(). It accepts additional arguments alpha and calibrate.

  • New el_sd() performs empirical likelihood test for the standard deviation.

  • New elmt() tests multiple hypotheses with empirical likelihood.

  • New weights() extracts the re-scaled weights from a model.

  • New formula() extracts the model formula used from a model.

  • New nobs() extracts the number of observations from a model.

  • New conv() extracts the convergence status from a model.

  • New logLR() extracts the log empirical likelihood ratio from a model.

  • el_control() gains additional arguments verbose, keep_data, seed, b, and m.

MINOR IMPROVEMENTS

  • cv argument in confint() and confreg() defaults to NULL. If non-NULL, level is ignored.

  • probit link produces a more accurate result in el_glm().

  • print() for an EL object shows whether the data are weighted or not.

  • All row or column names (if any) of input data are preserved in a fitted EL object.

BUG FIXES

  • confint() and confreg() check if the cv argument is compatible with the th value set by control_el().
