Power function πc(θ)的自变量是参数θ,隐变量是在参数取值为θ的情况下,拒绝了H0的概率。 Power function πc(θ)是对于拒绝域C来说的,对于每一个拒绝域C,就会有一条πc(θ)的函数曲线。 Power function πc(θ)既然是拒绝H0的概率,那么也一定与这个假设检验的设置有...
C Language: pow function(Power) In the C Programming Language, the pow function returns x raised to the power of y.SyntaxThe syntax for the pow function in the C Language is:double pow(double x, double y);Parameters or Argumentsx A value used in the calculation where x is raised to ...
The following example shows the usage of pow() function.#include <math.h> #include <stdio.h> int main(void) { double x, y, z; x = 2.0; y = 4.0; z = pow(x,y); printf("%lf to the power of %lf is %lf\n", x, y, z); x = 2.2; y = 3.2; z = pow(x,y); ...
在C 语言的最初定义中,可以在程序的开头按照下面这种形式声明 power 函数:int power(); 函数声明中不允许包含参数列表,这样编译器就无法在此时检查 power 函数调用的合法性。事实上,power 函数在默认情况下将被假定返回 int 类型的值,因此整个函数的声明可以全部省略。 在ANSI C 中定义的函数原型语法中,编译器可...
