72 Reference Information
Error/Message Description
Input must be
non-negative
Integer.
This error is returned when an input is not the
expected number type. For example, in
distribution arguments TRIALS and x in
Binomialpdf.
Input
must be Real
This error is returned when an input requires a
real number.
Invalid
data type
This error is returned when the argument of a
command or function is the incorrect data type.
For example, the error will be displayed for sin
(i) or min(i,7) where the arguments must be
Real numbers.
Invalid Dimension This error is returned when a matrix or vector
operation cannot be performed due to incorrect
dimensions.
Invalid
equation
This error is returned when an invalid equation
is entered such as 1000=10000 or a blank
equation in the numeric solver.
Invalid
Function
This error is returned when no function is
defined and a function evaluation is attempted.
Define functions in I.
List Dimension
1{dim(list){50
This error is returned when, in v:
• the SUM LIST function is executed on an
empty list
• a sequence is created with a length of 0 or
>50.
Max iterations
reached.
Try new guess.
This error is returned when the numeric
equation solver has exceeded the maximum
number of permitted iterations for finding a
solution. Change the initial guess for the
solution variable or check the equation.
Mean:
Enter mu>0
This error is returned when an invalid value is
input for the mean (mean = mu) in poissonpdf
or poissoncdf.
Memory limit
reached
This error is returned when a calculation
contains a circular reference such as two
functions referencing each other, or a very long
calculation.
No sign change
found.
Try new guess.
This error is returned when the numeric solver
algorithm cannot find a solution. Change the
initial guess for the solution variable or check
the equation.
Repeated roots equations, such as x^2=0, do
