Numerical feature simulation for positive samples. Called by createData

subtype1.feats = 1:5, subtype2.feats = 6:10, subtype3.feats = 11:15)
|
subtype |
Numeric number indicating which subtype to simulate. Currently supports three subtype: 1, 2 or 3. |
upper.mean |
The mean of the upper component of the bimodal Gaussian distribution from which features are simulated. |
lower.mean |
The mean of the lower component of the bimodal Gaussian distribution from which features are simulated. |
upper.sd |
The standard deviation of the upper component of the bimodal Gaussian distribution from which features are simulated. |
lower.sd |
The standard deviation of the lower component of the bimodal Gaussian distribution from which features are simulated. |
n.features |
Number of features to simulate. |
subtype1.feats |
Numeric vector representing the indices of features that define subtype 1. |
subtype2.feats |
Numeric vector representing the indices of features that define subtype 2. |
subtype3.feats |
Numeric vector representing the indices of features that define subtype 3. |
Simulations support 3 subtypes, each defined by 5 different features.
Subtype 1 is defined as having the first 3 subtype1.feats
and at least one of the next 2 subtype1.feats
simulated from the upper component of the bimodal Gaussian distribution.
Subtype 2 is defined as having all 5 subtype2.feats
simulated from the upper component.
Subtype 3 is defined as having the first 4 subtype3.feats
simulated from the upper component and and the last subtype3.feats
simulated from the lower component.
Returns a vector of simulated features
createCase
is not meant to be called alone. It is designed as a helper function for createData
.
