Statistic 2var with frequencies - Printable Version +- HP Forums (https://www.hpmuseum.org/forum) +-- Forum: HP Calculators (and very old HP Computers) (/forum-3.html) +--- Forum: HP Prime (/forum-5.html) +--- Thread: Statistic 2var with frequencies (/thread-3284.html) Statistic 2var with frequencies - salvomic - 03-06-2015 06:02 PM 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... Any help, please? Thanks in advance! Salvo RE: Statistic 2var with frequencies - Helge Gabert - 03-06-2015 08:42 PM 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. RE: Statistic 2var with frequencies - salvomic - 03-06-2015 09:13 PM (03-06-2015 08:42 PM)Helge Gabert Wrote:  I'd write a little utility program, something like this: EXPORT UTIL1() ... 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 RE: Statistic 2var with frequencies - Helge Gabert - 03-06-2015 10:12 PM Thanks for the typo correction!
