What is the purpose of pooling the results from each imputed data set?
What is the purpose of pooling the results from each imputed data set?
- To combine the optimal number of clusters and subset of selected variables that gives the highest CritCF in each imputed data set (correct)
- To randomly select the optimal number of clusters and subset of selected variables
- To discard the results from each imputed data set
- To calculate the mean of the optimal number of clusters and subset of selected variables
How can the optimal number of clusters (kfin) be decided?
How can the optimal number of clusters (kfin) be decided?
- It is determined by the mean CritCF value across all imputed data sets
- It is chosen randomly from any of the imputed data sets
- It is the most frequently selected one according to CritCF (correct)
- It is based on a purely subjective judgment
What method can be used to describe uncertainty in kfin associated with missing data?
What method can be used to describe uncertainty in kfin associated with missing data?
- Histogram plot
- Line plot
- Barplot of selection frequency for each value of k and boxplot of CritCF for each value of k (correct)
- Scatter plot
