npd_data_sim: Simulate the demand and attributes for new products

In npdsim: Simulate Demand and Attributes for New Products

Simulate the demand and attributes for new products

Description

Simulate the demand and attributes for new products during their life cycle by specifying their life cycle type of shape and providing information about their attributes.

Usage

npd_data_sim(
  products_number,
  periods_number,
  shape_number,
  shape_type = "random",
  level_number,
  level_range = 1000:10000,
  noise_cv = 0.05,
  attribute_type = "ind",
  attributes_number = 10,
  shape_attributes_number = 5,
  level_attributes_number = 3
)

Arguments

products_number	Number of products
periods_number	Number of periods of the introduction and growth phases
shape_number	Number of generic shapes
shape_type	Type of shape to generate. It can take the values: "triangle", "trapezoid", "bass", "random" and "intro & growth". The type "random" picks one of the types "triangle", "trapezoid", "bass" randomly for each product. The type "intro & growth" is used for the shapes of the introduction and growth phases.
level_number	Number of generic levels
level_range	Range of values from which the level is sampled
noise_cv	The coefficient of variation of the noise added to the simulated sales
attribute_type	Type of relationship between attributes and shape and level. There can be independent attributes or dependent attributes. attribute_type takes one of the two values: "dep" and "ind". Check 'attribute_sim_dep' and 'attribute_sim_dep'.
attributes_number	The number of attributes
shape_attributes_number	The number of attributes assigned to shape
level_attributes_number	The number of attributes assigned to level

Value

A date frame that contains the following columns: product_id, demand and attributes.

Examples

npd_data_sim(products_number=100,
