Fit nonlinear mixed-effects model (requires Statistics and Machine Learning Toolbox software)

`fitResults = sbiofitmixed(sm,grpData,responseMap,covEstiminfo)`

`fitResults = sbiofitmixed(sm,grpData,responseMap,covEstiminfo,dosing)`

`fitResults = sbiofitmixed(sm,grpData,responseMap,covEstiminfo,dosing,functionName)`

`fitResults = sbiofitmixed(sm,grpData,responseMap,covEstiminfo,dosing,functionName,opt)`

`fitResults = sbiofitmixed(sm,grpData,responseMap,covEstiminfo,dosing,functionName,opt,variants)`

`fitResults = sbiofitmixed(_,'UseParallel',tf)`

```
[fitResults,simDataI,simDataP]
= sbiofitmixed(_)

performs
nonlinear mixed-effects estimation using the SimBiology`fitResults`

,`grpData`

,`responseMap`

,`covEstiminfo`

)^{®} model `sm`

and
returns a `NLMEResults`

object `fitResults`

.

`grpData`

is a ```
groupedData
object
```

specifying the data to fit. `responseMap`

is
a character vector or cell array of character vectors that maps model
components to response data in `grpData`

. `covEstiminfo`

is
a `CovariateModel object`

or
an array of `estimatedInfo`

objects that defines
the parameters to be estimated.

If the model contains active doses and variants, they are applied during the simulation.

provides
an option to estimate parameters in parallel if Parallel

`[`

returns a vector of results objects `fitResults`

,`simDataP`

]
= sbiofitmixed(_)`fitResults`

,
vector of simulation results `simDataI`

using individual-specific
parameter estimates, and vector of simulation results `simDataP`

using
population parameter estimates.

`sbiofitmixed`

unifies`sbionlmefit`

and`sbionlmefitsa`

estimation functions. Use`sbiofitmixed`

to perform nonlinear mixed-effects modeling and estimation.`sbiofitmixed`

simulates the model using a`SimFunction object`

, which automatically accelerates simulations by default. Hence it is not necessary to run`sbioaccelerate`

before you call`sbiofitmixed`
