Compute pooled point estimates, standard error and degrees of freedom
according to the Von Hippel and Bartlett formula for Bootstrapped Maximum Likelihood
Multiple Imputation (BMLMI).
     
    
    
    Arguments
- ests
 
numeric vector containing estimates from the analysis of the imputed datasets.
 
- D
 
numeric representing the number of imputations between each bootstrap sample in the BMLMI method.
 
 
    
    Value
    a list containing point estimate, standard error and degrees of freedom.
     
    
    Details
    ests must be provided in the following order: the firsts D elements are related to analyses from
random imputation of one bootstrap sample. The second set of D elements (i.e. from D+1 to 2*D)
are related to the second bootstrap sample and so on.
