Statistical functions (COMPUTE command)

COMPUTE NewSalary = SUM(Salary,Raise).
COMPUTE MinValue = MIN(V1,V2,V3,V4).
COMPUTE MeanValue = MEAN(V1,V2,V3,V4).
COMPUTE NewMean = MEAN.3(V1,V2,V3,V4).
  • NewSalary is the sum of Salary plus Raise.
  • MinValue is the minimum of the values for V1 to V4.
  • MeanValue is the mean of the values for V1 to V4. Since the mean can be computed for one, two, three, or four values, MeanValue is assigned a valid value as long as any one of the four variables has a valid value for that case.
  • In the last example above, the .3 suffix specifies the minimum number of valid arguments required. NewMean is the mean of variables V1 to V4 only if at least three of these variables have valid values. Otherwise, NewMean is system-missing for that case.
