Start New Sampling Process
1. The first step in beginning a new
sampling process is to select a universe
using the browse button (Figure 1).
a. This universe should be a .csv file
that is local to your computer (Figure 2).
b. The file consists of a number of
rows. Each row represents a complete
scenario, and the values must be scaled
to the range of (- 1, 1) or proper scale
that can be signified by the distance
formulas (Figure 3). CSTEP also can
process a universe with percentage
rates format as well as general number
format. The user may exclude the scenario ID column in the input scenario
universe file. CSTEP automatically
will assign an ID number based on the
row number of the scenario.
c. All further progress in this program
will be determined by this universe.
2. After selecting the universe, you
choose its starting row and column to
ensure there are no problems with differences between .csv files. This can
be done either by selecting it from the
universe or by typing in a row and
NOTE: You may view the universe
at any time (after importing it) by
clicking the View Universe button
3. Optional: Choosing an original
ID column for your universe will tell
CSTEP where your scenario IDs are.
They will, otherwise, be numbered
from start row to the last row.
4. Once this information has been entered, the program will verify the data
of the parameters you entered.
5. You will then progress to the parameters tab of our program (Figure
6. On this tab you will enter information that pertains to the population (a
subset of your universe) on which you
will run calculations.
7. Here you will enter information
that defines your population, such as:
a. Scenario horizon
b. Population size
c. Number of samples
d. Nested samples (Figure 5 and
e. Sampling method (depending
on the method, you also will need a
weight or constant values).
f. Optional: Choosing an initial
