The input is a matrix [y_ik] and the output is a matrix obtained by applying formula (6) in this paper. One of the goals is to obtain an output matrix whose rows have equal variances. The method relies on various assumptions described in the paper. variance stabilizing transformation loess scale group transformation total intensity transformation single total intensity transformation paired quantile transformation mean centering median centering differential expression analysis pareto scaling dimensionality reduction probabilistic algorithm moving average replicate analysis data imputation loess transformation curve fitting descriptive statistics calculation network analysis sequence analysis polynomial transformation logarithmic transformation exponential transformation soft independent modeling of class analogy analysis regression analysis method discriminant analysis eh transformation b transformation s transformation visualization similarity calculation feature unit-variance scaling planned process entity occurrent process processual_entity definition editor definition source curation status alternative term example of usage preferred term definition relates a class to a property where instances of the class make sense as subjects of the property relates a class to a property where instances of the class make sense as objects of the property relates a class to a property where some instances of the class may make sense as subjects of the property relates a class to a property where some instances of the class may make sense as objects of the property has_input is_input_of has_output is_realized_as is_reagent_in is_realization_of utilizes_reagent is_instrument_for is_output_of utilizes_instrument adjacent_to agent_in contained_in contains has_agent has_integral_part has_part has_participant has_proper_part integral_part_of part_of participates_in preceded_by precedes proper_part_of relationship ready for release
