Class weights allow you to specify the weights for each class of the response variable. For
example, an observation from one class may weigh more than an observation from a different
class. Class weights are similar to prior probabilities and can help provide a more accurate
model.
- Unweighted
- Minitab does not weigh the classes.
- Weighted
to ensure equal sample sizes across classes
- Minitab automatically balances unequal class sizes so that the class
weights are proportional to the sample frequencies of classes.
- Specify
weights
- Enter a weight for each class. Class weights affect the model
generation and the model performance, but do not affect the class counts.
Class weights must be > 0.The default value is 1.
