The hmits of the intervals are 3,4,6 and 7 and the number of
values is 2,3 and 4. The table is stored as KZDAT for further
The routine is calculating a table from a discrete table
(XD AT) . The new table will include relative frequencies, (co-
lumn 4) cummulative frequencies (column 3) and cummula-
tive relative frequencies (column 5).
This routine transforms a class statistics to a discrete statis-
tics by using the mean value of each interval as the repre-
sentative value. The table is stored as £DAT. Input data is
KsDAT which is stored in advance.
The mean value and the standard deviation is calculated ba-
sed on a frequency table (F) or a two variable statistic table
