Problem with Sample stage
Posted: Fri May 26, 2006 4:16 am
The Sample stage when running in percent mode, is not giving the correct percentages to the output files.What is the significance of the random number generator concept and the 'Seed' value?.I am not able to make out the difference it makes to the output when the seed value is specified and when not specified.
Eg:My input file contains, 21 records and sampling it to 3 output files each 10,25,40 percentages respectively.But the output is not coming as expected ie.10% of 21,25% of 21 and 40% of 21 .Why is it so?.
