WitrynaSince the solution of many regression problems (including logistic regression) involves the computation intermediate $(X^TX)^{-1}$, it is then impossible to estimate the parameters of the model. Out of curiosity, you can check here how this term is involved in the formula of multiple linear regression. That was it for absolute rank deficiency. WitrynaA solution to this is to utilize a form of penalized regression. In fact, this is the original reason some of the penalized regression forms were developed (although they turned out to have other interesting properties.
