FTest

Ensor.FTest(Ensor* pEnsor1, Ensor* pEnsor2)

Parameters

• Ensor* pEnsor1

Ensor.new() 함수등에 의해 만들어진 포인터를 입력합니다(first data).

• Ensor* pEnsor2

Ensor.new() 함수등에 의해 만들어진 포인터를 입력합니다(second data).

Return Value

Ensor* pRetEnsor : Fcalc, 0.05 two tailed F,two tailedd probability P를 가진 Ensor*를 반환합니다.

Remarks

• Degrees of freedom(df1,df2)

  varianceP(pEnsor1) >= varianceP(pEnsor1) 이면  df1 = n1-1,df2=n2-1.
  
  varianceP(pEnsor1) < varianceP(pEnsor1) 이면 df1 = n2-1,df2=n1-1.
  
  n1 : first data elements' number
  
  n2 : second data elements' number
