Exemplos de sample_variance em C++ (Cpp)

Exemplo n.º 1

Arquivo: result_recorder.hpp Projeto: 0day-ci/gcc

      bool
      result_recorder<Value_Type>::
      add_result(value_type res)
      {
	m_l.push_back(res);
	m_sample_mean = sample_mean(m_l.begin(), m_l.end());
	m_sample_var = sample_variance(m_l.begin(), m_l.end(), m_sample_mean);

	size_t dist = std::distance(m_l.begin(), m_l.end());
	return sample_mean_confidence_checker(m_sample_mean, m_sample_var,
					      dist, 0.1);
      }

Exemplo n.º 2

Arquivo: statistics.c Projeto: ali-asaei/babak_lib

double one_sample_t(double *x, int n)
{
   double var;
   double mean;
   double t;

   if(n<2) 
   {
      return(0.0);
   }

   var = sample_variance(x,n,mean);

   if(var<=0.0) 
   {
      return(0.0);
   }

   t = sqrt(1.0*n)*mean/sqrt(var);

   return(t);
}
