#' SPECT Heart Data Set 
#' 
#' The dataset describes diagnosing of cardiac Single Proton Emission Computed Tomography (SPECT) images
#' Each of the patients is classified into two categories: normal and abnormal. 
#' The database of 267 SPECT image sets (patients) was processed to extract features 
#' that summarize the original SPECT images. As a result, 44 continuous feature pattern
#' was created for each patient. The pattern was further processed to obtain 22 binary feature patterns. 
#' The CLIP3 algorithm was used to generate classification rules from these patterns. 
#' The CLIP3 algorithm generated rules that were 84.0% accurate (as compared with cardilogists' diagnoses). 
#' SPECT is a good data set for testing ML algorithms; it has 267 instances that are descibed by 23 binary attributes.
#' In the imputation study, it can be treated as a categorical-only data. For detailed information, please refer to
