other arguments to TMB::oneStepPrediction |
One-step-ahead residuals are useful for assessing goodness-of-fit in latent variable models. This is a wrapper function for TMB::oneStepPredict (beta version). osar
tries the "fullGaussian" (fastest) method first and falls back to the "oneStepGaussianOffMode" (slower) method for any failures. Subsequent failures are dropped from the output and a warning message is given. Note, OSA residuals can take a considerable time to calculate if there are many individual fits and/or deployments are long. The method is automatically parallelized across 2 x the number of individual fits, up to the number of processor cores available.
