If desired, the probable errors and average deviations can now be computed by the usual formulas. 88. In case the observations are made directly upon the values of sev...eral quantities subject to certain conditions, we have n = g, and equation (79) reduces to v=^ from which the mean error of any observation may at once be computed from its weight. 89. Example. Taking the example in paragraph 34 on the measurement of the angles of a quadrilateral, we had for OBSERVATION EQUATIONS 2 1 = weight 3 2 2 1 for the CONDITION EQUATION Zl -L. Z 2 _|_ 2j5 _j_ z 4 4. 58 = (B) and for the NORMAL EQUATIONS 4 zi 4- z 2 4- z 3 + 58 = *i + 3 z 2 4- z a + 58 = (C) 2l _j_ Z2 _j- 3 z s + 58 = Solving these equations for the values of the unknown quantities and also for their weights, we have Zi = 8.
