Formulate a mathematical method to partition continuous variate observations into a small number of groups while preserving maximal information.
Developed a mathematical framework defining optimal interval boundaries for continuous variables.
Calculated specific numerical interval recommendations for variates following a normal distribution.
Established a mathematical formulation to determine group cutoffs that minimize information loss during data condensation.
Provided practical numerical values for boundary selection when partitioning normally distributed data into discrete intervals.
