Full Version: Statistic 2var with frequencies
You're currently viewing a stripped down version of our content. View the full version with proper formatting.
hi all,
I want to analyze this table with Statistic 2 var:
x_i: 1, 4, 6, 16
y_i: 41, 69, 82, 84
n_i: 4, 5, 6, 5 (practically: 20 tests divided into 4 groups)
I wouldn't write every item more times.
I should get regression parameters...

Salvo
I'd write a little utility program, something like this:

EXPORT UTIL1()
BEGIN
LOCAL k,j,n,m;
n:=SIZE(C3); // frequencies in C3
FOR m FROM 1 TO n DO
k:=C3(m);
FOR j FROM 1 TO k-1 DO
C1:=CONCAT(C1,C1(m)); // x_i in C1
C2:=CONCAT(C2,C2(m)); // y_i in C2
END;
END;
END;

and then analyze the data {C1, C2} in the stat 2var app.

thank you!
it works... only two little typo (parenthesis closed at the end of concat() function:
Code:
``` EXPORT UTIL1() BEGIN LOCAL k,j,n,m; n:=SIZE(C3); // frequencies in C3 FOR m FROM 1 TO n DO k:=C3(m); FOR j FROM 1 TO k-1 DO C1:=CONCAT(C1,C1(m)); // x_i in C1 C2:=CONCAT(C2,C2(m)); // y_i in C2 END; END; END;```

We could also add a function to reset data to only those with frequencies, to restart analysis...
However it's ok also so.

Thanks again
Thanks for the typo correction!
