In doing so, you just have to place it in the numerator, and place immediately left of the major division value. By adding a degree of bias to the regression estimates, ridge regression reduces the standard errors. 2 1 9 5}{ 7} \times 10 = 4.5993. (3), the score for RC=25 is calculated as follows. Their fingerprint patterns and ridge counts were compared with equal number of healthy age-matched control subjects (40 each) of both sexes. 2. (5).
