Service and Warranty Information B-13
STAT ¦You are attempting a linear regression with a vertical line.
¦Statistical analyses must have at least two data points;
QUADREG must have at least three data points.
¦The list of s (frequency) elements must be ≥ 0, and at
least one F value must be ≥ 0.
¦The frequency list, when used for “sorting” statistics
(median, Qã, Qå, or boxplot), must be an integer ≥ 0 and
99.
¦(XMAX.XMIN)àXSCL must be 31 for a histogram.
STAT PLOT You are trying to display a graph when there is a statistical
plot turned on that uses an undefined list.
SYNTAX The command contains a syntax error. Look for misplaced
functions, arguments, parentheses, or commas. See Appendix
A and the appropriate chapter.
UNDEFINED You are attempting to reference a variable that is not
currently defined. For example, a statistical variable , which
has no current value because a list has been edited, has been
referenced.
WINDOW RANGE There is a problem with the Window variables.
¦You may have defined XMAXXMIN, YMAXYMIN,
TSTEP=0, or TMAXTMIN and TSTEP>0 (or vice versa).
¦The Window variables are too small or too large to graph
correctly. This can occur if you attempt to zoom in or out
so far that you are not within the numerical range of the
calculator.
ZOOM A point or a line, rather than a box, is defined in ZBOX; or a
math error has resulted from a Zoom operation.
