LOAD DATA

Paste data in the table below, a column for each variable and a row for each sample.

Log distribution

n
Mean
Std. Deviation

Click on the plot to define the inflection point(s).
After defined, the inflection point(s) can be
altered by dragging with the mouse cursor.
# of subpopulations

Fit error: --------

After the inflection points are defined, the
generated subpopulations can be manually
adjusted by vertically dragging then (adjusting
the mean value) or dragging with the Ctrl key
pressed (adjusting the standard deviation)
