Perform Advanced Analysis

When you run advanced statistical analysis for data, you can do any of the following with the analysis results:

  • Open the results in a new window to save or print the results.
  • Download the R workspace in which the statistics were analyzed, for replication of the analysis. See Replicate Analysis for more information.
  • View citation information for the data analyzed, and for the full data set from which you selected variables to analyze. See View Citations for more information.

To run statistical models for selected variables:

  1. In the Data File page, click the Advanced Statistical Analysis tab.
  2. Scroll down the screen and click the check boxes to select variables from the table of available values. When you select a variable, it is added to the Selected Variables box at the top of the tab.
    To remove a variable from this box, deselect it from the Variable Type list at the bottom of the screen.
    To select all variables, click the check box beside the column name, Variable Type.
  3. Select a model from the Choose a Statistical Model drop-down list.
  4. Select one variable in the Selected Variables box, and then click the applicable arrow button to assign a function to that variable from within the analysis model.
    You see the name of the variables in the appropriate function box.
    Note: Some functions allow a specific type of variable only, while other functions allow multiple variable types. Types include Character, Continuous, and Discrete. If you assign an incorrect variable type to a function, you see an Incompatible type error message.
  5. Repeat the variable and function assignments until your model is complete.
  6. Select your Output options.
  7. Click the Run Model button.
    If the statistical model that you defined is incomplete, you first are prompted to correct the definition. Correct your model, and then click Run Model again.
    You see the Dataverse Analysis page.
  8. To save or print the results, scroll to the Advanced Statistical Analysis section and click the link Open results in a new window. You then can print or save the window contents.
    To save the analysis, scroll to the Replication section and click the button zipFile_<number>.zip.
    Review the Citation Information for the data set and for the subset that you analyzed.
  9. Click the link Back to Analysis and Subsetting to return the previous page and continue analysis of the data.
