Struct ProductModel 

Source 
pub struct ProductModel { /* private fields */ }
Expand description

Implementation of the LogNormal price distribution model. The model takes the following expectations:

  • the most popular price value
  • the most popular price range
  • the expected share of the popular price range of all prices (normally - 2/3 of all)

The model then finds the parameters of the LogNormal distribution that best fit the given expectations and uses these to sample prices for modeled products.

Implementations§

Source§

impl ProductModel

Source

pub fn top_price(&self) -> f64

The most popular price value

Source

pub fn top_low(&self) -> f64

Lower bound of the most popular price range

Source

pub fn top_high(&self) -> f64

Upper bound of the most popular price range

Source

pub fn top_share(&self) -> f64

The expected share of the popular price range of all prices (normally - 2/3 of all)

Source

pub fn tolerance(&self) -> f64

Source

pub fn pivot_price(&self) -> f64

The median price at which customer losts 1/2 of interest in the product, compared to the maximum.

Source

pub fn interest_loss_rate(&self) -> f64

The higher the value – the steeper the interest loss curve around the pivot price.

Source

pub fn new() -> Arc<Self>

Source

pub fn builder() -> ProductModelBuilder

Creates a new builder for this struct.
