Then it is obvious that A-1 is defined
The "Pic" part only applies to the widescreen calculators, not the 89 or 89 Titanium: 130: Argument must be a string: 140: Argument must be a variable name This can also indicate an invalid variable name such as SINGULAR MATRIX
Then enter the “type” of variable as “matrix” by entering
The SinReg instruction or a polynomial regression generated a singular matrix
Find the 2-3 entry, the diagonal entries, first row, and second column of B
So wait, do you have a TI-89 or a TI-84 Plus SE? Anyway, you can’t “change the equation” to make it work because matrix A has a determinant of zero, which means
This error occurs when you attempt to invert a singular matrix, which
The problem is that the stiffness matrix of the linear system is singular and the linear solver
A singular matrix is a matrix that cannot be inverted, or, equivalently, that has determinant zero
The error number to the left is not displayed, but is stored to the errornum system variable, which can be
Zeros appear above
A selection screen will appear

So we do not have the ability to write V\D*V and get something that makes sense
Conclusion
Students can solve the problem using the TI-Nspire file
1 Gmin stepping failed
However, after I get far along towards convergence, the Hessian gets close to singular
The Mahalanobis distance requires you to calculate the inverse of the covariance matrix
Using Reduced row-echelon form (rref) to Solve Linear Systems It is often easier to store the matrix you are working on in a memory location
The reason why the comparison might be misleading is that the two models have different meanings: being able to reduce the deviance by introducing a behavior (the intercept) that was not reflected in the original model might be scientifically

Please refer to the examples listed below: Correct method to perform the inverse of a matrix: Incorrect method to perform the inverse of a matrix: Please see the TI-83 Family and TI-84 Plus Family guidebooks for additional information
Models with nonlinear optimization cannot handle singular design matrices or singular hessian

Your matrix A, however, is not of full rank since rows A[1] and A[2] are not lineraly independent
