Medmed; Mid() - Texas Instruments TI-Nspire Reference Manual

median()
,
Matrix1 freqMatrix
median( [
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

X Y Freq
MedMed , [, ] [,
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
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.

mid()

sourceString Start
mid( , [,
Returns Count characters from character string sourceString,
beginning with character number Start.
If Count is omitted or is greater than the dimension of sourceString,
returns all characters from sourceString, beginning with character
number Start.
|
Count must be 0. If Count = 0, returns an empty string.
