X~2检验应用甚广,但公式较多,计算费时。为提高工作效率,简捷求得X~2值,现以CaSiO fx-180p 型及同类功能的计算器编制一个通用X~2检验计算程序。只输入自由度[n′=(r-1)(c-1)]和实际数(A),可直接求四格表、R×2、2×C 和间接求R×C 表(校正X~2值除外)X~2值。现介绍如下。1 程序清单INV KAC MODE O INV PCL P_1 The X~2 test is widely used, but the formula is more and the calculation is time-consuming. In order to improve work efficiency, the value of X~2 is simply obtained. Now, a general X~2 test calculation program is compiled with a calculator of CaSiO fx-180p type and similar functions. Only the degree of freedom [n’=(r-1)(c-1)] and the actual number (A) are input, and the square table, R×2, 2×C, and indirect R×C tables can be directly found (correction X Except for ~2 value) X~2 value. The introduction is as follows. 1 Program List INV KAC MODE O INV PCL P_1
