StatsOne()

Type: REGULAR FUNCTION

Purpose: Calculate statistical information on a set of data.

The data set can include all of the data in a DATACOL object, or a subset of the data in a DATACOL object. The calculated statistics are returned as members of a VECTOR.

Usage: Result = StatsOne (DataCol, FirstPoint, LastPoint)

 

DataCol

DATACOL

The column of data upon which to calculate the statistics.

 

FirstPoint

INDEX

The first point to include in the data set (Optional)

  LastPoint INDEX The last point to include in the data set (Optional)
  Result VECTOR

[0] N Sum(1)

[ 1] Mean Sum(X)/N

[ 2] StdVar Sum(X–Xm)2/N–1

[ 3] StdDev sqrt(StdVar)

[ 4] 1st moment Sum(abs(X–Xm))/N

[ 5] 2nd moment Sum((X–Xm)2)/N

[ 6] 3rd moment Sum((X–Xm)3)/N

[ 7] 4th moment Sum((X–Xm)4)/N

[ 8] PopVar Sum((X–Xm)2)/N

[ 9] PopDev sqrt(PopVariance)

[10] RMS sqrt(Sum(X2)/N)
