Homogeneity equation
WebWhere O is the observed value in a cell, E is the expected value, the formula is (O – E)²/E. For the first cell, we get (2 - 2.6)²/2.6 = 0.14. If we repeat the same calculation for the cells excluding the totals and add them up, this give a value of 5.8. This is the test statistic. To compute a p-value, we need to know the degrees of freedom. Web24 mrt. 2024 · (1) and the homogeneous equation is (2) (3) Now attempt to convert the equation from (4) to one with constant coefficients (5) by using the standard transformation for linear second-order ordinary differential equations. Comparing ( 3) and ( 5 ), the functions and are (6) (7) Let and define (8) (9) (10) (11) Then is given by (12) (13) (14)
