What to print.  Default is "fit".  If you input what as a vector, print returns a list. See examples.
- "model" The model parameters with names for the estimated parameters.  The output is customized by the form of the model that was fit.  This info is in -  attr(x$model, "form") .
 
- "par"  A list of only the estimated values in each matrix. Each model matrix has it's own list element. Standard function: - coef(x)
 
- "start" or "inits"  The values that the optimization algorithm was started at. Note, - x$startshows this in form="marss" while- printshows it in whatever form is in-  attr(x$model, "form") .
 
- "paramvector"  A vector of all the estimated values in each matrix. Standard function: - coef(x, type="vector").  See- coef.
 
- "par.se","par.bias","par.lowCIs","par.upCIs"  A vector the estimated parameter standard errors, parameter bias, lower and upper confidence intervals. Standard function: - MARSSparamCIs(x)See- MARSSparamCIs.
 
- "xtT" or "states"  The estimated states conditioned on all the data. - x$states
 
- "data"  The data. This is in - x$model$data
 
- "logLik"  The log-likelihood. Standard function: - x$logLik.  See- MARSSkffor a discussion of the computation of the log-likelihood for MARSS models.
 
- "ytT"  The expected value of the data conditioned on all the data.  Returns the data if present and the expected value if missing. This is in - x$ytT(ytT is analogous to xtT).
 
- "states.se"  The state standard errors. - x$states.se
 
- "states.cis"  Approximate confidence intervals for the states. See - MARSSparamCIs.
 
- "model.residuals"  The one-step ahead model residuals or innovations. \(\mathbf{y}_t - E[\mathbf{y}_t|\mathbf{y}_1^{t-1}]\), aka actual data at time \(t\) minus the expected value of the data conditioned on the data from \(t=1\) to \(t-1\). Standard function: - residuals(x, type="tt1")See- MARSSresidualsfor a discussion of residuals in the context of MARSS models.
 
- "state.residuals"  The smoothed state residuals. \(\mathbf{x}_t^T-E[\mathbf{x}_t|\mathbf{x}_{t-1}^T]\), aka the expected value of the states at time \(t\) conditioned on all the data minus the expected value of the states at time \(t\) conditioned on \(\mathbf{x}_{t-1}^T]\). Standard function: - residuals(x, type="tT")See- MARSSresiduals.
 
- parameter name  Returns the parameter matrix for that parameter with fixed values at their fixed values and the estimated values at their estimated values. Standard function: - coef(x, type="matrix")$elem
 
- "kfs"  The Kalman filter and smoother output.  See - MARSSkffor a description of the output. The full kf output is not normally attached to the output from a- MARSS()call.  This will run the filter/smoother if needed and return the list invisibly.  So assign the output as- foo=print(x,what="kfs")
 
- "Ey"  The expectations involving y conditioned on all the data.  See - MARSShatytfor a discussion of these expectations.  This output is not normally attached to the output from a- MARSS()call--except- ytTwhich is the predicted value of any missing y. The list is returned invisibly so assign the output as- foo=print(x,what="Ey").
