circumference coefficient
1.In the multiple regression model vital capacity as dependent variable, height, chest circumference and sitting height were sent into the model, standardized coefficient of the mode was 0.903 in boys and 0.802 in girls; pulmonary ventilation as dependent variable, age and body weight were entered as predictors, standardized coefficient of the mode was 0.736 in boys and 0.748 in girls.
2.In the paper we study the relation between the circumference c(G) of the connected graph G and the monomial coefficient a 1 of its color palymonial,and obtain inequality|a 1|≥c(G)-1.Equality is true iff G only includes a cycle.
