A team of researchers collects and publishes detailed information about factors that affect heart disease. Variables include age, sex, cholesterol levels, maximum heart rate, and more. This example is based on a public data set that gives detailed information about heart disease. The original data are from archive.ics.uci.edu.
The researcher can use the random forest classification tree model to predict response class probabilities for new observations.
|Rest Blood Pressure||140||140|
|Max Heart Rate||150||165|
|Chest Pain Type||2||1|
|Fasting Blood Sugar||1||1|
Minitab uses the Random Forests® model in the results to estimate the class probability of a heart disease diagnosis event for the two sets of prediction values. The researchers find that the probability of a heart disease diagnosis event using the specified settings is approximately 0.63 for the first set and 0.52 for the second set.
