  • Fix bug where models where omega boundary warnings caused problems
    in estimation (#490)

  • Created a new api for pre-processing ui, allowing adding arbitrary
    hooks. As written now, this includes literal fix and zero omega as
    well as added the new rxode2 ui processing.

  • Fixed compilation to only use -I in most systems for maximum
    compatibility

nlmixr2est 3.0.1

New features

  • Now when optimizing only a single parameter with focei-family,
    will change to use stats::optimize() for the outer problem (#481)

  • When estimating with all fixed population parameters, do a posthoc
    estimation.

  • Internally removed assignInMyNamespace() replacing with
    nlmixr2global, which fixes some edge case bugs where the nlmixr2
    environment was not reset properly.

  • Treated edge case where all initial parameters are zero and change
    scaling from scaled to unscaled (#486)

  • Added mu4 referencing that will change string expressions to
    rxode2 numeric values. This allows derived strings to also be
    treated as mu expressions (#484)

Bug Fixes

  • Fix focei covariance step when many omega values are fixed #482

nlmixr2est 3.0.0

  • No binary linking to rxode2, lbfgsb3c and n1q1, which means
    that updating these will not make nlmixr2est crash without
    recompiling.

  • New mu3 referencing will take context from the model to see if the
    algebraic expression can be completed from defined model variables;
    These variable would have to be unique.

What's Changed

  • 451 one rxode2 no longer any sub packages except rxode2ll by @mattfidler in #452
  • As observed by babelmixr2 sometimes the ui is not present; handle this by @mattfidler in #457
  • Error in saem code generation when all fixed effect parameters are fixed by @mattfidler in #461
  • Invalid index warning in nlmixr2 fits by @mattfidler in #463
  • It is no longer there. I will add it back. by @mattfidler in #460
  • Warnings suppressed when using nlmixr2 with "rxSolve" estimation method. by @mattfidler in #453
  • All models created by nlmixr2 should add the model based interpolation (and any other properties) when building other sorts of models by @mattfidler in #456
  • tableControl() incompatible options should error with addDosing items by @mattfidler in #464
  • Read relevant tableControl() options from nlmixr2 and override control=rxControl() by @mattfidler in #465
  • Use lotri nearPD by @mattfidler in #467

Breaking changes

  • Saem non-mu reference input parameters/covariates were fixed so they
    work correctly with fixed parameters (Issue #445)

  • Focei changed back to having a lower bound for standard deviations
    when not specified. This means that best model fits may change. You
    can revert to the old settings by using
    foceiControl(sdLowerFact=0.0). You can also change the factors to
    other values than the default value, that is
    foceiControl(sdLowerFact=0.000001) for instance which would
    multiply the initial value by 0.000001 when either the lower bound
    isn't specified or the lower bound is specified as zero for the
    error estimates related to error-based standard deviations.

  • In nlmixr2, expressions are optimized. Because of that
    optimization, numerical rounding differences can cause different
    directions in optimization when fixing parameters in the model
    vs. fixing the parameters manually.

    This means that the fixed parameters in a model vs hard-coded fixed
    parameters could give different values in the final model.

    A new option literalFix was introduced which change the fixed
    population parameters to constants in the model while running the
    optimization. This makes the output of fixing within the model and
    fixing manually the same (which is what is likely expected). The
    default is for this to be turned on (ie. literalFix=TRUE). You
    can get back the old behavior by using the option
    literalFix=FALSE.

  • In saem, the monte-carlo sampling occurs for all parameters
    including non-informative ETAs. A fix ensure that non-informative
    etas in saem are fixed to zero while sampling the phi values.
    This may change results for models with uninformative etas. To
    ignore the uninformative etas with saem you ca use use the prior
    saem handling with saemControl(handleUninformativeEtas=FALSE).

New features

  • Gracefully degrade when $cov is not in the right form (see #423)

  • Add support for PopED in place solving (used in babelmixr2)

  • If est=foceiControl() or other nlmixr2 control with the class
    foceiControl infer the estimation method is focei

nlmixr2est 2.2.1

  • Align with the possibility that linCmt sensitivities may not be
    present (like intel c++)

Bug fix

  • focei cache needs to be based on the parameter order as well as
    the model information (#415)

What's Changed

  • 415 nlmixr2est focei needs to cache based on thetaomega order by @mattfidler in #416

New Features

  • Algebraic mu referencing has been implemented in nlme and saem.

  • New estimation method "nlm" has been added to estimate population
    only likelihoods using stats::nlm and possibly return a
    standardized nlmixr2 fit.

  • New estimation method "nls" has been added to estimate population
    only problems. This uses minpack.lm::nlsNM by default if
    present, or the stats::nls

  • New estimation method "optim" has been added to estimate population
    only likelihoods. This uses stats::optim and returns a
    standardized nlmixr2 fit.

  • New estimation method "nlminb" has been added to estimate population
    only likelihoods. This uses stats::nlminb and returns a
    standardized nlmixr2 fit.

  • New estimation methods from the minqa package: "bobyqa", "uobyqa"
    and "newuoa" have been added to estimate population only
    likelihoods. These methods returns a standardized nlmixr2 fit.

  • New estimation method "lbfgsb3c" to estimate population only
    likelihoods. This returns a standardized nlmixr2 fit.

  • New estimation method "n1qn1" to estimate population only
    likelihoods. This returns a standardized nlmixr2 fit.

  • Added new feature for vpcSim() where a minimum number of subjects
    are simulated from the model when trying to fill in ODEs that were
    not solved successfully. By default this is 10. This also
    works-around a bug when there is only one subject simulated and the
    data.frame has a slightly different output.

Breaking changes

  • Removed fit$saemTransformedData since it isn't actually used in
    saem anymore (but will break anyone's code who is using it)

  • Now the internal function .foceiPreProcessData() requires the
    rxode2 control rxControl() because some of the new steady state
    lag features need to translate the data differently based on
    rxControl() options.

Bug fixes

  • Printing models with correlated omega values and omega values fixed
    to zero no longer fails (#359)

  • Add back values for $parHistData (#368)

  • This requires a new rxode2 which will fix multiple endpoint issues observed (#394)

  • Manual back-transformed values in $parFixed are now displaying
    correctly and are calculated based on the confidence interval in the
    control instead of 95% confidence no matter what (#397)

Other changes

  • An as.rxUi() method was added for fit models (#377)

nlmixr2est 2.1.8

  • Version bump and a minor documentation update (same as nlmixr2est
    2.1.7). This version bump is to simply allow correct binary linkage
    to rxode2 2.0.14. Otherwise nlmixr2 models will crash R.

nlmixr2est 2.1.7

  • As requested by CRAN, remove Rvmmin

  • Values in $parFixed for BSV without exponential transformation are now
    correctly shown (#366)

Breaking changes

  • Since rxode2 now allows simulation with omega having diagonal
    zero elements, $omega and $omegaR now reflects this information
    including the zero omega elements in the output. On the other hand,
    the other eta-information and standard error information for zero
    etas are still excluded in $phiR, $phiSE, $eta etc.

Bug fixes

  • vpcSim() works when an eta value is fixed to 0 (#341)

  • augPred() now consistently uses the simulation model (instead of
    the inner model used for CWRES calculation).

  • Add $fitMergeFull, $fitMergInner, $fitMergeLeft,
    $fitMergeRight as a complement to $dataMergeFull,
    $dataMergInner, $dataMergeLeft, $dataMergeRight. The fit
    variants prefer columns in the fit dataset instead of the original
    dataset. This is useful for goodness of fit plots with censoring
    since the DV in the fit simulates values under the ipred/residual
    assumption and will give more appropriate goodness of fits,
    otherwise these values are the limit of whatever censoring is
    applied

  • Moved the mu reference fix for the split mu referenced model here
    (from babelmixr2)
