Type of the boosting algorithm.

Possible values are listed below. Gentle AdaBoost and Real AdaBoost are often the preferable choices.

• Discrete Discrete AdaBoost.
• Real Real AdaBoost. It is a technique that utilizes confidence-rated predictions and works well with categorical data. This is the default.
• Logit LogitBoost. It can produce good regression fits.
• Gentle Gentle AdaBoost. It puts less weight on outlier data points and for that reason is often good with regression data.
