_D_e_s_c_r_i_p_t_i_o_n:

     Functions that perform predictions using NADA model objects.

     For 'ros' models, predict the normal quantile of a value.

     For 'cenfit' objects, predict the probabilities of new
     observations.

_U_s_a_g_e:

     ## S4 method for signature 'ros':
     predict(object, newdata, ...)

     ## S4 method for signature 'cenfit':
     predict(object, newdata, conf.int=FALSE, ...)

     ## S4 method for signature 'cenreg':
     predict(object, newdata, conf.int=FALSE, ...)

     ## S4 method for signature 'cenfit':
     pexceed(object, newdata, conf.int=FALSE, ...)

     ## S4 method for signature 'ros':
     pexceed(object, newdata, conf.int=FALSE, ...)

_A_r_g_u_m_e_n_t_s:

  object: An output object from a NADA function such as 'ros'. 

 newdata: Numeric vector of data for which to predict model values. For
          'ros' objects this will be new normalized quantiles  of
          plotting positions.  For 'cenfit' objects this will be new
          observations for which you desire the modeled probabilities. 

conf.int: A logical indicating if confidence intervals should be
          computed.  For 'cenfit' objects, the confidence interval is
          set during the call to 'cenfit'.  Currently not supported for
          'ros'  objects. 

     ...: Additional arguments passed to the generic method.
