discordant pairs造句

• The Kendall tau distance between two series is the total number of discordant pairs.
• Where P is the number of concordant pairs and Q is the number of discordant pairs ( inversions ).
• The sum \ sum a _ { ij } b _ { ij } is twice the number of concordant pairs minus the number of discordant pairs ( see Kendall tau rank correlation coefficient ).
• The Kendall tau rank correlation coefficient, which measures how closely related two series of numbers are, is proportional to the difference between the number of concordant pairs and the number of discordant pairs.
• An estimate of Goodman and Kruskal's gamma, another measure of rank correlation, is given by the ratio of the difference to the sum of the numbers of concordant and discordant pairs.
• Somers "'D " is another similar but asymmetric measure given by the ratio of the difference in the number of concordant and discordant pairs to the number of pairs with unequal values for one of the two variables.
• As \ tau ( X, X ) quantifies the number of pairs with unequal values, Somers " D " is the difference between the number of concordant and discordant pairs, divided by the number of pairs with values in the pair being unequal.
• A final phase of the study will look at " discordant pairs, " cases in which an accident was minor but injuries were severe, and other cases in which the cars suffered large amounts of damage but the children did not, to find out what went wrong and what went right.
• For a group of twins in which at least one member of each pair is affected, " probandwise concordance " is a measure of the proportion of twins who have the illness who have an affected twin and can be calculated with the formula of 2C / ( 2C + D ), in which C is the number of concordant pairs and D is the number of discordant pairs.
