What is aggregate data?

Aggregate data is essentially summarized data. Minitab can analyze aggregate data for generalized linear models. In generalized linear models, these columns summarize the number of occurrences of combinations of response and predictors.

For example, you can do a binary logistic regression analysis of this data. The number of occurrences of each combination of response and predictors is in the frequency column. The first row shows that the combination of High Setting, Fast Speed, and Strength of 140 occurred three times in this data set.
