WebAug 27, 2024 · It is also useful if there is something wrong with the imputation model that we should fix. The behavior is, however, frustrating if the model in question fails to converge in, say, iteration 7 on m=42. By then, the respective model has successfully converged 416 times (assuming the default burin-in) before it failed -- once. WebA possible reason is that a search direction could not be computed despite several attempts to modify the iteration matrix. Usually, the value of the regularization parameter then becomes too large. One situation where this can happen is when values in the Hessian are invalid (NaN or Inf).
