Which node will merge these two data sources?

  • A. Append node
  • B. Filter node
  • C. Aggregate node

Answer : A

You have a data set with numeric fields (columns) that contain null values. You want to replace each of these null values with the value of zero.
Which node will you use to accomplish this task?

  • A. Type node
  • B. Filler node
  • C. Filter node
  • D. Binning node


Answer : C

Professional without being explicitly defined by users? (Choose two.)

  • A. Null or system-missing values
  • B. String with value "%NULL%"
  • C. Blank missing values
  • D. Numeric set to NaN


Answer : B,D

You are provided with a data set that includes daily maximum temperatures at an airport.
Your analysis requires you to create a new field containing the maximum temperature from five days ago.
Which node would be used for this purpose?

  • A. History node
  • B. Filler node
  • C. Transpose node
  • D. Binning node


Answer : A

You have executed a model node which has generated a model nugget connected to your stream's data source.
What will allow the stream to score data with this new nugget?

  • A. Remove any partition node to allow all data to be scored.
  • B. Add a Discriminant node to use the nugget model for scoring.
  • C. Remove the Reclassify node to use the nugget model for scoring.
  • D. Add an output node downstream from the nugget.


Answer : C

You need to output only a list of field names, arranged in a single column, for a reporting function. You have already imported the data using a Database node and know it has
25,000 records.
Which node sequence would yield the desired output?

  • A. Database > Filter > Transform > Table
  • B. Database > Transform > Filter > Table
  • C. Database > Filter > Transpose > Table
  • D. Database > Transpose > Filter > Table

You have a data set with two different date fields (columns). Your analysis requires you to create a new field which is the number of calendar days elapsed between these two dates.
Which node will you use to accomplish this task?

  • A. Filter node
  • B. Type node
  • C. Derive node
  • D. Reclassify node


Answer : C

A customer has a large data set with no target variables or known results and is looking for a good approach for understanding more about groups within the data set.
Which two IBM SPSS Modeler Professional node applications represent a correct approach to accomplish this task? (Choose two.)

  • A. The customer uses a Kohonen node in an effort to group data into clusters using a self- organizing map of neurons.
  • B. The customer uses a TwoStep node to identify the optimal set of clusters within the data.
  • C. The customer uses a RFM Aggregate node to identify the optimal set of clusters within the data.
  • D. The customer uses a Carma node in an effort to group data into clusters using a self- organizing map of neurons.


Answer : A,B

What is the primary purpose of the Partition node in a modeling effort?

  • B. Increase the proportion of under-represented subgroups within the data.
  • C. Decrease the proportion of an over-represented subgroup within the data.
  • D. Allow for equal sampling across subgroups within the data.
