mydata: Data Generator

In snn: Stabilized Nearest Neighbor Classifier

Description

Generate random data from mixture Gaussian distribution.

Usage

mydata(n, d, mu = 0.8, portion = 1/2)

Arguments

n	The number of observations (sample size).
d	The number of variables (dimension).
mu	In the Gaussian mixture model, the first Gaussian is generated with zero mean and identity covariance matrix. The second Gaussian is generated with mean a d-dimensional vector with all mu and identity covariance matrix.
portion	The prior probability for the first Gaussian component.

Value

Return the data matrix with n rows and d + 1 columns. Each row represents a sample generated from the mixture Gaussian distribution. The first d columns are features and the last column is the class label of the corresponding sample.
