On the Analysis and Synthesis of a Four‐Field‐Table
K. Hellmich · Biometrical Journal · 1983
The real four‐field‐table measure k is calculable as follows: K1 for V(a, b, c, d) with k1 = (arc K1)/100, K11 for V(a, b, 0, 0) with k11 = (arc K11)/100, K12 for V(c, d, 0, 0) with k12 = (arc K12)/100 and K121 for V(0, 0, c, d) with k121 = –k12. The equation k1 = k11 – k12 holds good. It is possible to calculate the probability of error of a four‐field‐table with small frequencies, indirectly from component values. Two examples are given.
