It must be the time (after midnight) as I have a blackout.
I have a matrix with some missing values I want to fill. for a certain cell, I know that the marginal row probability has mean r (more specifically, the marginal row probability follows the beta distribution with some parameters I know). the marginal column distribution of that cell has mean c (it follows a beta distribution with different known parameters)
what value should I "plug" in that cells (or which probability to sample from, in filling that value?)

עיתוי בעייתי זה סיפור חיי :)
בכל מקרה תחשוב על טבלאות שכיחות שבהן יודעים את סכומי הטורים והשורות, ומנסים למלא את התאים עצמם. מצד אחד יש הרבה פתרונות אפשריים, מצד שני ההתפלגות הפוסטריורית על התא, בהינתן סכום הטור והשורה שונה מההתפלגות הפריורית, מה שאומר שיש שם מה ללמוד.
