Cushing's Syndrome Hormone Levels with Patient Types

Containing measurements of Tetrahydrocortisone and Pregnanetriol hormone levels for patients with Cushing's syndrome, with a Type classification for most patients. It has 4 columns: patient label, two hormone measurements, and a type. The type for the last six patients is unknown.

Use Cases

• Classify patient Type based on Tetrahydrocortisone and Pregnanetriol measurements using logistic regression.
• Analyze the distribution of Tetrahydrocortisone levels across different Type categories.
• Impute the unknown Type for patients u1 to u6 based on their hormone level patterns.

Strengths

• Includes two specific, measured biochemical features (Tetrahydrocortisone and Pregnanetriol).
• Explicitly identifies 6 rows with unknown Type, useful for testing imputation or semi-supervised learning.

Limitations

• Small sample size; the total number of rows is not specified but is implied to be low.
• Contains missing labels (Type) for a subset of patients, requiring special handling.
