The Excel MDETERM function is used to determine the multiple determination coefficient (R2) of a regression equation. The R2 coefficient is a measure of how well the regression equation fits the data. The higher the R2 coefficient, the better the fit. The Excel MDETERM function is used to calculate the R2 coefficient for a two-variable regression equation.
The syntax of the MDETERM function in Excel is as follows: MDETERM(array, determinant) The MDETERM function calculates the determinant of a matrix given as an array argument.
MDETERM is a function in Excel that is used to determine the matrix determinant of a given matrix. The function takes two arguments- the first is the matrix that you wish to calculate the determinant of, and the second is an array of integers that specifies the order of the matrix. The function will return the determinant of the matrix as a decimal value. An example of how to use the MDETERM function in Excel is shown below:
This function will calculate the determinant of the matrix that is contained in the cell A1, and will use the integers contained in the cells B1 through B3 to specify the order of the matrix.
There are a few occasions when you should not use the MDETERM function in Excel. One is when you are trying to determine the inverse of a matrix, as the MDETERM function is not designed to do that. Additionally, the MDETERM function should not be used when you are trying to find the determinant of a matrix that is too large, as Excel will not be able to calculate the determinant accurately.
There are a few similar formulae to MDETERM in Excel. The first is Determinant, which is found under the Statistics tab and is used to calculate the determinant of a square matrix. The second is Matrix Inverse, which is also found under the Statistics tab and is used to calculate the inverse of a square matrix. The third is Eigenvalues and Eigenvectors, which are found under the Analysis tab and are used to calculate the eigenvalues and eigenvectors of a square matrix.
