Regression coefficient (slope of a straight line). Correlation coefficient; also used for scratch. The x-value of a data pair when entering data; the hypothetical x when projecting yˆ ; or xˆ (x-estimate) when given a hypothetical y. The y-value of a data pair when entering data; the hypothetical y when projecting xˆ; or yˆ (y-estimate) when given a hypothetical x. Statistical accumulation and computation. Example 1: Fit a straight line to the data below. Make an intentional error when keying in the third data pair and correct it with the undo routine. Also, estimate y for an x value of 37. Estimate x for a y value of 101. X 40.5 38.6 37.9 36.2 35.1 34.6 Y 104.5 102 100 97.5 95.5 94 Keys: (In RPN mode) S Display: value Description: Starts straight-line routine.
