Diabetes dataset
Ten baseline variables, age, sex, body mass index, average bloodpressure, and six blood serum measurements were obtained for each of n =442diabetes patients, as well as the response of interest, a quantitative measureof disease progression one year after baseline.
**Data Set Characteristics:**
Number of Instances: 442
Number of Attributes: First 10 columns are numeric predictive values
Target: Column 11 is a quantitative measure of disease progressionone year after baseline
Attribute Information:
- age age in years
- sex
- bmi body mass index
- bp average blood pressure
- s1 tc, T-Cells (a type ofwhite blood cells)
- s2 ldl, low-densitylipoproteins
- s3 hdl, high-densitylipoproteins
- s4 tch, thyroidstimulating hormone
- s5 ltg, lamotrigine
- s6 glu, blood sugar level
Note: Each of these 10 feature variables have been mean centered andscaled by the standard deviation times `n_samples` (i.e. the sum of squares ofeach column totals 1).

糖尿病数据集
对442例糖尿病患者，分别获得了10个基线变量、年龄、性别、体重指数、平均血压和6个血清测量值，以及兴趣反应（基线后一年疾病进展的定量测量）。
**数据集特征：**
实例数：442
属性数：前10列是数值预测值
目标：第11列是基线检查后一年疾病进展的定量测量
属性信息：
- age 年龄（以年为单位）
- sex 性别
- bmi 体重指数
- bp 血压平均值
- s1 tc，T细胞（一种白细胞）
- s2 低密度脂蛋白
- s3 高密度脂蛋白，高密度脂蛋白
- s4 tch，促甲状腺激素
- s5 ltg，拉莫三嗪
- s6 血糖，血糖水平
注：这10个特征变量中的每一个都以平均值为中心，并按标准差乘以“n_samples”（即每列的平方和总计为1）进行缩放。
