    any sample for chi-square working

    canny yue

      Hi everyone,

       

      WINDOW_SUM(

          (SUM([x])-WINDOW_AVG(SUM([x]))) *

          (SUM([y])-WINDOW_AVG(SUM([y]))) )

      /

      (  SQRT(WINDOW_SUM(SQUARE(SUM([x])-WINDOW_AVG(SUM([x]))))) *

          SQRT(WINDOW_SUM(SQUARE(SUM([y])-WINDOW_AVG(SUM([y]))))) )

       

       

      This is the formula for chi-square? can someone explain for me, cause i don't understand this formula. or who can give me a sample for chi-square?

       

      Thanks

      canny
