| In large scale surveys the assumption of missingness at random is untenable. |
| A Bayesian methodology permits modeling different patterns of missingness under ignorability and nonignorability assumptions. |
| This method permits modeling different patterns of missingness under ignorable and nonignorable assumptions, and a multinomial-Dirichlet model is used to estimate the cell probabilities which can help to predict the winner. |
| This procedure leads to three missingness mechanisms. |
| Gazing at the crisscrossing lines of Manhattan or the blue vastness of the oceans, I would feel something I could only describe as missingness. |
| These methods use local properties of the likelihood to test for sensitivity to various assumptions about the missingness mechanism. |
