how to find the point spread of $d how to estimate the point spread of gellman gelman's score differential analysis what is the score differential in gelman's bda what is the normal approximation of value in bda3 gelman bda definition where does the cumulative distribution in the cumulative phi distribution (x) come from what does d =$ where does score differential $-$ point spread come from where does each $phi value on the cumulative distribution of $d textn come from? which of the following is an approximation of the score differential? when to use a normal approximation what is the value of a normal approximation in gelman what is the score in the bda3 textbook exercise? what is the value for score differential in gellman's bda3 how to approximation scores where does the cumulative distribution below come from what is the average score differential of $-$ what is normal approximation of $d where does each value of the cumulative distribution come from?
