The binomial coefficient is the number of ways of picking unordered outcomes from possibilities, also known as a combination or combinatorial number. therefore gives the number of k-subsets possible out of a set of distinct items. For example, The 2-subsets of are the six pairs , , , , , and , so . The number of lattice paths from the origin to a point ) is the binomial coefficient (Hilton and Pedersen 1991).
In statistics, correlation is connected to the concept of dependence, which is the statistical relationship between two variables. The Pearsonâs correlation coefficient or just the correlation coefficient r is a value between -1 and 1 (-1â¤râ¤+1). It is the most commonly used correlation coefficient and valid only for a linear relationship between the variables. If r=0, no relationship exist, and if râ¥0, the relation is directly proportional; the value of one variable increases with the increase in the other.
