Abstract
Zadatak ovog završnog rada bio je detaljno objasniti pojam statisticke veze između varijabli razlicitog tipa. Korelacija predstavlja međusobnu povezanost između pojava koje su različite, a predstavljene su vrijednostima dviju varijabli. Ukoliko se vrijednost jedne varijable mijenja, mijenja se vrijednost i druge varijable. Pearsonov koeficijent korelacije mjeri jakost i smjer linearne korelacije. Spearmanov koeficijent korelacije izračunava se kod ispitivanja korelacije dviju varijabli ranga, tj. kod ispitivanja povezanosti dvaju redosljednih obilježja. Kendallov koeficijent korelacije ranga procjenjuje stupanj slicnosti između dva skupa rangova danih istom skupu objekata. Cramerov koeficijent korelacije definira se za analizu snaga povezanosti dviju nominalnih varijabli s ’N’ broja kategorija u svakoj. Navedeni koeficijenti korelacije imaju gornju granicu 1 za bilo koju tablicu nepredvidenih slučajeva veličine. Korelaciju je moguće primjeniti u svim inženjerskim strukama te je u ovom radu gubitak kapaciteta baterije, iskazan pomocu Pearsonovog koeficijenta, prikaz primjene u elektrotehnici.
Abstract (english)
The assignment of this study was detailed description of statistical link connecting different types of variables. Correlation expresses the link between different occurrences, described with values of two different variables. Pearson’s correlation coefficient measures the strenght and the direction of linear correlation. Evaluation of the correlation between two rank variables defines Spearman’s correlation coefficient. Kendall’s rank correlation coefficient estimates the degree of similarity between two sets of ranks given to the same set of objects. Cramer’s correlation coefficient is defined to analyze the strengths of the correlation between two nominal variables with the ’N’ number of categories in each. Described correlation coefficients have an upper limit of 1 for any contingency table of magnitude. It is possible to implement correlation in all engineering professions, the loss of batery capacity defined with the Pearson’s correlation coefficient is a demonstration in electrical engineering.
