Data Set Information:

该数据集由一系列生物医学语音测量数据组成，这些数据来自42名早期帕金森病患者，他们被招募参加为期6个月的远程症状进展监测远程监测设备试验。这些录音是在患者家中自动拍摄的。

表中的列包含受试者编号、受试者年龄、受试者性别、从基线招募日期开始的时间间隔、运动UPDR、总UPDR和16项生物医学语音测量。每行对应于这些人5875个语音记录中的一个。数据的主要目的是预测16个语音测量的运动和UPDRS总分（“运动和UPDRS”和“总UPDRS”）。

The data is in ASCII CSV format. The rows of the CSV file contain an instance corresponding to one voice recording. There are around 200 recordings per patient, the subject number of the patient is identified in the first column. For further information or to pass on comments, please contact Athanasios Tsanas (tsanasthanasis '@' gmail.com) or Max Little (littlem '@' physics.ox.ac.uk).

The dataset was created by Athanasios Tsanas (tsanasthanasis '@' gmail.com) and Max Little (littlem '@' physics.ox.ac.uk) of the University of Oxford, in collaboration with 10 medical centers in the US and Intel Corporation who developed the telemonitoring device to record the speech signals. The original study used a range of linear and nonlinear regression methods to predict the clinician's Parkinson's disease symptom score on the UPDRS scale.
