median( ) median(Matrix1[, freqMatrix]) ⇒ matrix Returns a row vector containing the medians of the columns in Matrix1. Each freqMatrix element counts the number of consecutive occurrences of the corresponding element in Matrix1. Notes: • All entries in the list or matrix must simplify to numbers. • Empty (void) elements in the list or matrix are ignored. For more information on empty elements, see page 131. MedMed MedMed X,Y [, Freq] [, Category, Include]] Computes the median-median line y = (m·x+b) on lists X and Y with frequency Freq. A summary of results is stored in the stat.results variable. (See page 97.) All the lists must have equal dimension except for Include. X and Y are lists of independent and dependent variables. Freq is an optional list of frequency values. Each element in Freq specifies the frequency of occurrence for each corresponding X and Y data point. The default value is 1. All elements must be integers | 0. Category is a list of numeric or string category codes for the corresponding X and Y data. Include is a list of one or more of the category codes. Only those data items whose category code is included in this list are included in the calculation. For information on the effect of empty elements in a list, see "Empty (void) elements" on page 131.
