Submodules

dowhy.interpreters.confounder_distribution_interpreter module

class dowhy.interpreters.confounder_distribution_interpreter.ConfounderDistributionInterpreter(estimate, fig_size, font_size, var_name, var_type, **kwargs)

Bases: VisualInterpreter

Parameters:

• estimate – Causal estimate

• fig_size – Size of the figure

• font_size – Size of the font of the plot title

• var_name – The confounding variable for which distribution changes should be compared

• var_type – Type of the confounding variable; must be one of ‘continuous’ or ‘discrete’

SUPPORTED_ESTIMATORS = [<class 'dowhy.causal_estimators.propensity_score_weighting_estimator.PropensityScoreWeightingEstimator'>]

static discrete_dist_plot(labels, not_treated_counts, treated_counts, ax, title, var_name, font_size, width=0.35)

Plot of the treated vs untreated.

interpret(data: DataFrame)

Shows distribution changes for confounding variables before and after applying inverse propensity weights.

dowhy.interpreters.propensity_balance_interpreter module

class dowhy.interpreters.propensity_balance_interpreter.PropensityBalanceInterpreter(estimate, **kwargs)

Bases: VisualInterpreter

Initialize an interpreter.

Parameters:

instance – An object of type CausalModel, CausalEstimate or CausalRefutation.

SUPPORTED_ESTIMATORS = [<class 'dowhy.causal_estimators.propensity_score_stratification_estimator.PropensityScoreStratificationEstimator'>]

interpret(data: DataFrame)

Balance plot that shows the change in standardized mean differences for each covariate after propensity score stratification.

dowhy.interpreters.textual_effect_interpreter module

class dowhy.interpreters.textual_effect_interpreter.TextualEffectInterpreter(instance, **kwargs)

Bases: TextualInterpreter

Initialize an interpreter.

Parameters:

instance – An object of type CausalModel, CausalEstimate or CausalRefutation.

SUPPORTED_ESTIMATORS = ['all']

interpret(data: DataFrame)

Interpret causal effect by showing how much a unit change in treatment will cause change in the outcome.

dowhy.interpreters.textual_interpreter module

class dowhy.interpreters.textual_interpreter.TextualInterpreter(instance, **kwargs)

Bases: Interpreter

Base class for interpreters that show text as output.

Initialize an interpreter.

Parameters:

instance – An object of type CausalModel, CausalEstimate or CausalRefutation.

show(interpret_text)

Display the interpretation.

Parameters:

interpret_text – String containing the interpretation

Returns:

None

dowhy.interpreters.visual_interpreter module

class dowhy.interpreters.visual_interpreter.VisualInterpreter(instance, **kwargs)

Bases: Interpreter

Base class for interpreters that show plots or visualizations as output.

Initialize an interpreter.

Parameters:

instance – An object of type CausalModel, CausalEstimate or CausalRefutation.

show(interpret_plot)

Display the intepretation.

Parameters:

interpret_plot – Plot object containing the interpretation

Returns:

None
