mvpa2.misc.data_generators.chirp_linear(n_instances, n_features=4, n_nonbogus_features=2, data_noise=0.4, noise=0.1)

Generates simple dataset for linear regressions

Generates chirp signal, populates n_nonbogus_features out of n_features with it with different noise level and then provides signal itself with additional noise as labels
