Minimum number of rows required to shuffle data

data

Vector of variables in 'data' to transform.

Details

'Shuffling' refers to the a random sampling of a variable without replacement e.g. [A, B, C] becoming [B, A, C] but not [A, A, B]. "Grouped shuffling" refers to aggregating the data by another feature before applying the shuffling process. Grouped shuffling will preserve aggregate level metrics (e.g. mean, median, mode) but removes ordinal properties i.e. correlations and auto-correlations
