Data Set Information:

Impedance measurements were made at the frequencies: 15.625, 31.25, 62.5, 125, 250, 500, 1000 KHz

Impedance measurements of freshly excised breast tissue were made at the follwoing

frequencies: 15.625, 31.25, 62.5, 125, 250, 500, 1000 KHz. These measurements plotted in the (real, -imaginary) plane constitute the impedance spectrum from where the breast tissue features are computed.

The dataset can be used for predicting the classification of either the original 6 classes or of 4 classes by merging together the fibro-adenoma, mastopathy and glandular classes whose discrimination is not important (they cannot be accurately discriminated anyway).

Attribute Information:

I0 Impedivity (ohm) at zero frequency

PA500 phase angle at 500 KHz

HFS high-frequency slope of phase angle

DA impedance distance between spectral ends

AREA area under spectrum

A/DA area normalized by DA

MAX IP maximum of the spectrum

DR distance between I0 and real part of the maximum frequency point

P length of the spectral curve

Class car(carcinoma), fad (fibro-adenoma), mas (mastopathy), gla (glandular), con
