Bases:
ModelFitterLogistic-growth model fitter with regularized least-squares objective.
Logistic Kinetics Model:
\[N(t) = \frac{K}{1 + \frac{K - N_0}{N_0} e^{-rt}}\]\(N_t\): population size at time \(t\)
\(N_0\): initial population size at time \(t\)
\(r\): growth rate
\(K\): carrying capacity (maximum population size)
From this we derive:
\[\mu_{\max} = \frac{K r}{4}\]\(\mu_{\max}\): maximum specific growth rate
Loss Function:
To solve for the parameters, we use the following loss function with the SciPy linear least-squares solver:
\[J(K, N_0, r) = \frac{1}{n}\sum_{i=1}^{n} \frac{1}{2}\left(f_{K,N_0,r}(t^{(i)}) - N_t^{(i)}\right)^2 + \lambda\left(\left(\frac{dN}{dt}\right)^2 + N_0^2\right) + \beta \frac{\lvert K - \max(N_t) \rvert}{N_t}\]\(\lambda\): regularization term for growth rate and initial population size
- \(\beta\): penalty term for deviations in carrying capacity relative to
the largest measurement
- Output column naming:
analyzeemits metric-qualified columnsLogGrowthModel_<metric>_<parameter>(e.g. fittingon="Shape_Area"yieldsLogGrowthModel_Area_randLogGrowthModel_Area_µmax), plus qualified fit-quality columnsModelMetrics_<metric>_<label>. The<metric>segment isself.onwith a recognized measurement-category prefix stripped.- Attributes:
lam (float): The penalty factor applied to growth rates. beta (float): The maximum penalty factor applied to the carrying
capacity.
- Kmax_label (str | None): The column name for the maximum carrying capacity
values, if provided.

- classmethod __get_pydantic_json_schema__(core_schema: CoreSchema, handler: GetJsonSchemaHandler, /) JsonSchemaValue#
Hook into generating the model’s JSON schema.
- Parameters:
core_schema (CoreSchema) – A pydantic-core CoreSchema. You can ignore this argument and call the handler with a new CoreSchema, wrap this CoreSchema ({‘type’: ‘nullable’, ‘schema’: current_schema}), or just call the handler with the original schema.
handler (GetJsonSchemaHandler) – Call into Pydantic’s internal JSON schema generation. This will raise a pydantic.errors.PydanticInvalidForJsonSchema if JSON schema generation fails. Since this gets called by BaseModel.model_json_schema you can override the schema_generator argument to that function to change JSON schema generation globally for a type.
- Returns:
A JSON schema, as a Python object.
- Return type:
JsonSchemaValue
- __init__(**data: Any) None#
Create a new model by parsing and validating input data from keyword arguments.
Raises [ValidationError][pydantic_core.ValidationError] if the input data cannot be validated to form a valid model.

- __pretty__(fmt: Callable[[Any], Any], **kwargs: Any) Generator[Any]#
Used by devtools (https://python-devtools.helpmanual.io/) to pretty print objects.
- classmethod __pydantic_init_subclass__(**kwargs: Any) None#

Runs once per concrete subclass after pydantic has built its model, copying parameter descriptions parsed from the Google-style
Args:docstring block onto each field’sdescriptionslot.- Parameters:

- classmethod __pydantic_on_complete__() None#
This is called once the class and its fields are fully initialized and ready to be used.
This typically happens when the class is created (just before [__pydantic_init_subclass__()][pydantic.main.BaseModel.__pydantic_init_subclass__] is called on the superclass), except when forward annotations are used that could not immediately be resolved. In that case, it will be called later, when the model is rebuilt automatically or explicitly using [model_rebuild()][pydantic.main.BaseModel.model_rebuild].

Configuration for the model, should be a dictionary conforming to [ConfigDict][pydantic.config.ConfigDict].
- classmethod model_construct(_fields_set: set[str] | None = None, **values: Any) Self#
Creates a new instance of the Model class with validated data.
Creates a new model setting __dict__ and __pydantic_fields_set__ from trusted or pre-validated data. Default values are respected, but no other validation is performed.
- !!! note
model_construct() generally respects the model_config.extra setting on the provided model. That is, if model_config.extra == ‘allow’, then all extra passed values are added to the model instance’s __dict__ and __pydantic_extra__ fields. If model_config.extra == ‘ignore’ (the default), then all extra passed values are ignored. Because no validation is performed with a call to model_construct(), having model_config.extra == ‘forbid’ does not result in an error if extra values are passed, but they will be ignored.
- Parameters:
_fields_set (set[str] | None) – A set of field names that were originally explicitly set during instantiation. If provided, this is directly used for the [model_fields_set][pydantic.BaseModel.model_fields_set] attribute. Otherwise, the field names from the values argument will be used.
values (Any) – Trusted or pre-validated data dictionary.

ValidationError – If json_data is not a JSON string or the object could not be validated.
- Return type:
- classmethod model_validate_strings(obj: Any, *, strict: bool | None = None, extra: Literal['allow', 'ignore', 'forbid'] | None = None, context: Any | None = None, by_alias: bool | None = None, by_name: bool | None = None) Self#
Validate the given object with string data against the Pydantic model.
- Parameters:
obj (Any) – The object containing string data to validate.
strict (bool | None) – Whether to enforce types strictly.
extra (Literal['allow', 'ignore', 'forbid'] | None) – Whether to ignore, allow, or forbid extra data during model validation. See the [extra configuration value][pydantic.ConfigDict.extra] for details.
context (Any | None) – Extra variables to pass to the validator.
by_alias (bool | None) – Whether to use the field’s alias when validating against the provided input data.
by_name (bool | None) – Whether to use the field’s name when validating against the provided input data.
- Returns:
The validated Pydantic model.

Return the most recent fit results produced by

Plot model predictions alongside measurements with optional filtering.
- Parameters:
tmax (int | float | None) – Upper bound of the prediction curve. If
None, uses the maximum observed time.criteria (Dict[str, Union[Any, List[Any]]] | None) – Column/value filter applied to both fitted results and raw measurements before plotting.
figsize – Matplotlib figure size. Used only when
axis None.cmap (str | None) – Matplotlib colormap name, a single color string, or
Nonefor matplotlib’s default color cycle.legend (bool | str) – Controls legend rendering.
True(default) renders the legend with one entry pergroupbycombination, labeled by the firstgroupbycolumn.Falsehides the legend. A string must be one ofself.groupby; groups sharing a value in that column share both color and a single legend entry. The legend is auto-removed if it is larger than the axes.ax (plt.Axes | None) – Existing axes to draw into. A new figure is created when omitted.
**kwargs – Styling overrides —
dpi,facecolor,edgecolor,line_width,marker_size,elinewidth,capsize,legend_loc,legend_fontsize,label.
