Running the Analysis

  1. To run a Bayesian one sample - normal distribution analysis, from the menus choose: Analyze > Bayesian Statistics > One Sample Normal
    Figure 1. Bayesian One Sample Inference: Normal dialog box
    Bayesian One Sample Inference: Normal dialog box
  2. In the Bayesian One Sample Inference: Normal dialog, select logsalary and logsalbegin as Test Variable(s).
  3. Select Estimate Bayes Factor as the Bayesian Analysis. The Estimate Bayes Factor option constitutes a natural ratio to compare the marginal likelihoods between a null and an alternative hypothesis.
  4. Set the following values in the Data Variance and Hypothesis Values table:
    1. Set the logsalary variable's Null Test Value value to 10.35. The value specifies the null value that is used in the Bayes factor estimation.
    2. Set the logsalbegin variable values:
      1. Enable the Variance Known setting. Note that the g Value setting is automatically set to 1.
      2. Enter 0.12 as the Variance Value. The value specifies the variance value for observed data.
      3. Enter 9.50 as the Null Test Value. The value specifies the null value that is used in the Bayes factor estimation.
  5. Click OK in the Bayesian One Sample Inference: Normal dialog.
