ChisqTest

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

Parameters

• Ensor* pEnsor1

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

• Ensor* pEnsor2

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

Return Value

Ensor* pRetEnsor : Right tailed probability 와 계산된 F, df를 가진 Ensor*를 반환합니다.

Remarks

• The χ2 test first calculates a χ2 statistic using the formula:

  

  where:

  Aij = actual frequency in the i-th row, j-th column

  Eij = expected frequency in the i-th row, j-th column

  r = number or rows

  c = number of columns

• Degrees of freedom(df)

    r > 1 and c > 1 이면  df = (r - 1)(c - 1).
  
    r = 1 and c > 1 이면 df = c - 1.
  
    r > 1 and c = 1 이면 df = r - 1.
  
    r = c= 1은 허용되지 않습니다.
