Use the 'sMethod' parameter. Available methods include 'RNOWEIGHT' (unweighted estimate based on subgroup ranges), 'SNOWEIGHT' (unweighted estimate based on subgroup standard deviations), 'RMVLUE', 'SMVLUE', and 'RMSDF'.

What is the primary input table for the mChart action? How can I save the control limits to an output table? Is it possible to generate a chart only when control limits are exceeded? What does the 'limitN' parameter do? What is the purpose of the spc.mChart action?
