Tutorials

These tutorials work with the GOLDMineR demo program

• Tutorial 1: Beginning a GOLDMineR® Analysis
• NEW! Tutorial 2: Assessing the Effects of a Reminder Call
This tutorial illustrates:
• The use of the goodness of fit statistic to examine the validity of the scaling and other assumptions made by a model
• Obtaining various tables and regression plots
• The poor prediction and biased parameter estimates that can result from model misspecification (i.e., use of improper scores)
• NEW! Tutorial 3: Analysis of a Qualitative Predictor Variable
This tutorial illustrates:
• How to assess the overall model fit
• How to determine whether fixed or free scores are best for a given categorical predictor
• The relationship between probabilities, odds and logits
• How to use the effects plot to interpret the beta effect estimates of the predictors under different contrast coding
• How to change the contrasts without re-estimating the model
• Use of the effects plot to compare the observed with the expected log-odds ratios

Examples

These data examples provide a good illustration of GOLDMineR 2.0 but are not step-by-step tutorials

• Detailed example with qualitative predictor
• Stouffer's American Soldier Data
• GOLDMineR® in biomedical research
