Clustering analysis can be used to identify groups of similar lottery numbers by grouping numbers based on their characteristics, such as frequency of occurrence, adjacent number patterns, or the sums of drawn numbers. First, historical lottery data is collected and pre-processed to extract relevant features. Then, clustering algorithms like K-means or hierarchical clustering are applied to categorize the numbers into distinct clusters. This analysis helps reveal patterns, such as common combinations or frequently drawn numbers, which may assist in making more informed selections, though it’s important to remember that lottery draws are ultimately random.
