The datasets contain just sessions with valid data, extracted from clinical information of 98,015 hemodialysis sessions corresponding to 758 patients. 22 clinical parameters measured 5 times during the session, as well as the gender and age of the patient. Each dataset consists of a matrix where the rows are the sessions and the columns are the different clinical parameters (attributes), except for hypotension, which is the parameter to be classified and predicted (categorical response). It is important to point out that, to build this dataset, only the sessions where all the values of the clinical parameters are valid have been taken into account, that is, parameters that have been correctly measured (they do not contain null values or values outside their own ranges). There are 11 datasets, each of which consists of an increasing number of parameters (from only 2 parameters in the first dataset to 24 parameters in the last one).


Steps to reproduce

Datasets files are in CSV format. File "datasets.pdf" shows the parameters considered for each of the 11 datasets. The identity parameters (sex and age) are present in all the datasets, whereas the clinical parameters are included successively in the experiments, mostly in pairs, following a criterion of interest according to the possible influence of the clinical variables on the appearance of hypotension.
