Struct ABTestAnalyzer

pub struct ABTestAnalyzer;

Expand description

Statistical analyzer for A/B tests

Implementations§

impl ABTestAnalyzer

pub fn analyze(test: &ABTest) -> ABTestResults

Analyze an A/B test and return results

pub fn bayesian_analysis(test: &ABTest) -> BayesianAnalysis

Perform Bayesian analysis using Beta-Binomial model

Returns probability that treatment is better, expected lift, and credible intervals

pub fn calculate_effect_size(test: &ABTest) -> EffectSize

Calculate effect size metrics (Cohen’s h, relative risk, odds ratio, NNT)

pub fn check_srm(test: &ABTest) -> SRMCheck

Check for Sample Ratio Mismatch (data quality issue)

SRM occurs when the observed traffic split differs from expected, indicating a bug in randomization or data collection

pub fn sequential_analysis( test: &ABTest, analysis_number: u32, planned_analyses: u32, ) -> SequentialTest

Sequential testing with O’Brien-Fleming alpha spending

Allows valid early stopping while controlling Type I error

pub fn comprehensive_analysis(test: &ABTest) -> ComprehensiveAnalysis

Comprehensive analysis combining all methods

Returns actionable insights focused on what matters for users:

Should we ship this change?
Is the effect meaningful (not just statistically significant)?
Are there data quality issues?
What’s the risk of making the wrong decision?

Blanket Implementations§

impl<T> Any for T
where T: 'static + ?Sized,

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

impl<T> Borrow<T> for T
where T: ?Sized,

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

impl<T> BorrowMut<T> for T
where T: ?Sized,

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more

impl<T> Downcast for T
where T: Any,

fn into_any(self: Box<T>) -> Box<dyn Any>

Converts Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>, which can then be downcast into Box<dyn ConcreteType> where ConcreteType implements Trait.

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Converts Rc<Trait> (where Trait: Downcast) to Rc<Any>, which can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

fn as_any(&self) -> &(dyn Any + 'static)

Converts &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Converts &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

impl<T> DowncastSend for T
where T: Any + Send,

fn into_any_send(self: Box<T>) -> Box<dyn Any + Send>

Converts Box<Trait> (where Trait: DowncastSend) to Box<dyn Any + Send>, which can then be downcast into Box<ConcreteType> where ConcreteType implements Trait.

impl<T> DowncastSync for T
where T: Any + Send + Sync,

fn into_any_sync(self: Box<T>) -> Box<dyn Any + Sync + Send>

Converts Box<Trait> (where Trait: DowncastSync) to Box<dyn Any + Send + Sync>, which can then be downcast into Box<ConcreteType> where ConcreteType implements Trait.

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send>

Converts Arc<Trait> (where Trait: DowncastSync) to Arc<Any>, which can then be downcast into Arc<ConcreteType> where ConcreteType implements Trait.

impl<T> From<T> for T

fn from(t: T) -> T

Returns the argument unchanged.

impl<T> Instrument for T

fn instrument(self, span: Span) -> Instrumented<Self>

impl<T, U> Into<U> for T
where U: From<T>,

fn into(self) -> U

impl<T> IntoEither for T

fn into_either(self, into_left: bool) -> Either<Self, Self>

Converts self into a Left variant of Either<Self, Self> if into_left is true. Converts self into a Right variant of Either<Self, Self> otherwise. Read more

fn into_either_with<F>(self, into_left: F) -> Either<Self, Self>
where F: FnOnce(&Self) -> bool,

Converts self into a Left variant of Either<Self, Self> if into_left(&self) returns true. Converts self into a Right variant of Either<Self, Self> otherwise. Read more
