%%  Data Set Information:
%%  
%%  To demonstrate the RFMTC marketing model (a modified version of RFM), this study 
%%  adopted the donor database of Blood Transfusion Service Center in Hsin-Chu City 
%%  in Taiwan. The center passes their blood transfusion service bus to one 
%%  university in Hsin-Chu City to gather blood donated about every three months. To 
%%  build a FRMTC model, we selected 748 donors at random from the donor database. 
%%  These 748 donor data, each one included R (Recency - months since last 
%%  donation), F (Frequency - total number of donation), M (Monetary - total blood 
%%  donated in c.c.), T (Time - months since first donation), and a binary variable 
%%  representing whether he/she donated blood in March 2007 (1 stand for donating 
%%  blood; 0 stands for not donating blood).

%%  Attribute Information:
%%  
%%  Given is the variable name, variable type, the measurement unit and a brief 
%%  description. The "Blood Transfusion Service Center" is a classification problem. 
%%  The order of this listing corresponds to the order of numerals along the rows of 
%%  the database.
%%  
%%  R (Recency - months since last donation),
%%  F (Frequency - total number of donation),
%%  M (Monetary - total blood donated in c.c.),
%%  T (Time - months since first donation), and
%%  a binary variable representing whether he/she donated blood in March 2007 (1 
%%  stand for donating blood; 0 stands for not donating blood).
%%
%%  
%%  Table 1 shows the descriptive statistics of the data. We selected 500 data at 
%%  random as the training set, and the rest 248 as the testing set.
