Struct Geometric 

pub struct Geometric { /* private fields */ }

Geometric(p) over k=1,2,… counts trials until first success.

Implementations

impl Geometric

pub fn new(p: f64) -> Result<Self, DistError>

pub fn p(&self) -> f64

Trait Implementations

impl Clone for Geometric

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Geometric

impl Debug for Geometric

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Discrete for Geometric

fn pmf(&self, k: i64) -> f64

pmf(x)
