To add a collaborator to this project you will need to use the Relish gem to add the collaborator via a terminal command. Soon you'll be able to also add collaborators here!
More about adding a collaboratorgenerate multivariate correlated pseudorandom scalar attributes
in order to quickly create complex domains
a world creator should be able to create populations with multivariate correlated pseudorandom scalar attributes
- Scenarios
-
- weakly-correlated scalar feature pair
- strongly-correlated scalar feature pair
- arbitrarily-correlated scalar feature pair
- multiple features with covariance matrix
-
- Given
- a feature "height" with mean 80 and standard deviation 20
- And
- a feature "weight" with mean 150 and standard deviation 15
- And
- "height" and "weight" are weakly correlated
- When
- a large population is sampled
- Then
- "height" and "weight" should be weakly correlated
- And
- the empirical rule should hold
-
- Given
- a feature "height" with mean 80 and standard deviation 40
- And
- a feature "weight" with mean 150 and standard deviation 30
- And
- "height" and "weight" are strongly correlated
- When
- a large population is sampled
- Then
- "height" and "weight" should be strongly correlated
- And
- the empirical rule should hold
-
- Given
- a feature "height" with mean 80 and standard deviation 45
- And
- a feature "weight" with mean 160 and standard deviation 50
- And
- "height" and "weight" are 30% correlated
- When
- a large population is sampled
- Then
- "height" and "weight" should be 30% correlated
- And
- the empirical rule should hold
- multiple features with covariance matrix
-
- Given
- a feature "height" with mean 80 and standard deviation 25
- And
- a feature "weight" with mean 150 and standard deviation 30
- And
- a feature "foot_size" with mean 10 and standard deviation 3
- And
- "height" and "weight" are strongly correlated
- And
- "weight" and "foot_size" are weakly correlated
- And
- "height" and "foot_size" are 90% correlated
- When
- a large population is sampled
- Then
- "height" and "weight" should be strongly correlated
- And
- "weight" and "foot_size" should be weakly correlated
- And
- "height" and "foot_size" should be 90% correlated
- And
- the empirical rule should hold
