This is data file    TANG2.DAT
Effect of Factors on Apache/Linux Net Processing Time
2**(5-1) Fractional Factorial Design with replicated center points
Response variable                  = processing time (seconds)
Number of observations             = 16
Number of variables per line image = 7
Order of variables on a line image--
   1. Response variable   = processing time (seconds)
   2. Factor 1            = drop rate (2 levels--0%      and .4%)
   3. Factor 2            = bandwidth (2 levels--5 Mb    and 10 Mb)
   4. Factor 3            = delay     (2 levels--0 sec   and 5 sec)
   5. Factor 4            = file size (2 levels--28.8 kb and 1536 kb)
   6. Factor 5            = file type (2 levels--text    and image)
