Asymptote a horizontal, vertical, or slanted line that a graph approaches but never touches coefficient of determination A statistic that measures how well a regression prediction approximates the real data points. An r^2 of 1 indicates that the regression prediction is a perfect fit for the data common ratio The number by which each term in a sequence is multiplied to find the next number in the sequence; for example 4 is the common ratio for the sequence [1, 4, 16, 64, 256...]...
