Logistic regression singular matrix error
Witryna10 lip 2024 · Basic algebra tells us that a multipleregression linear equation can't be solved when the matrix is singular. A singular matrix means that the X columns in your input table are correlated. Remove them and try. Use the correlation node to find a matrix of correlations and filter the highly correlate ones out completely or keep 1 of … WitrynaThis results in the Singular Matrix error. This error also occurs if a calculation (typically a regression) produces a singular matrix. For more information on the algorithm …
