Med. 22 (1983) pp. 93-101. | | (b) The data was used for comparing 16 different discriminant | techniques, each trying to predict the state of the | thyroid gland. | | - (a) Coomans, D. and I.

Some achieve 100% correct classification. | |4. Relevant Information Paragraph: | | Five lab. tests are used to try to predict whether a patient's | thyroid to the class euthyroidism, hypothyroidism or | hyperthyroidism. The diagnosis (the class label) was based | on a complete medical record, including anamnesis, scan etc. | |5. Number of Instances | | 215 | |6. Number of Attributes | | 5 | |7. For Each Attribute: (please give both acronym and full name if both exist) | | Attr. no : | | 1: Class attribute (1 = normal, 2 = hyper, 3 = hypo) | 2: T3-resin uptake test. (A percentage) | 3: Total Serum thyroxin as measured by the isotopic | displacement method. | 4: Total serum triiodothyronine as measured by radioimmuno | assay. | 5: basal thyroid-stimulating hormone (TSH) as measured by | radioimmuno assay. | 6: Maximal absolute difference of TSH value after injection of | 200 micro grams of thyrotropin-releasing hormone as compared | to the basal value. | | All attributes are continuous. | | (Note, there is a slight possibility of having the | attribute numbers mixed up, see [2a] if it matters.) | | |8. Missing Attribute Values: how many per each attribute? | | None | |9. Class Distribution: number of instances per class | | Class 1: (normal) 150 | Class 2: (hyper) 35 | Class 3: (hypo) 30 | 1, 2, 3 | classes 2: continuous. 3: continuous. 4: continuous. 5: continuous. 6: continuous.
