Calculation of the difference of two proportions and any confidence interval for this difference, however, must be done in a DATA step. I have written a SAS(R) macro to calculate exact confidence intervals for the difference of two proportions based on an algorithm previously only implemented in...
I'm using SAS v9.4. Is there a macro that I can use to calculate confidence intervals for sensitivity/specificity for correlated data? Thank you in advance.0 Likes 1 ACCEPTED SOLUTION sharonlee Quartz | Level 8 Re: Confidence Interval calculation for sensitivity/specificity ...

Alternatively, the NULLSNPS= option can be used to specify biallelic markers other than those in the VAR statement to be used to calculate λˆ. This allows markers that are assumed to Statistical Computations 57 have no effect on disease susceptibility or to not be in linkage disequilibrium ...
The point is, SAS has to compute the asymptotic variance to calculate the confidence interval, so why not just go ahead and display it? (Yes, I understand that the confidence interval is symmetric only on a log scale.)Addendum: R doesn’t either. Same story. Weird. . Related Profile ...

The t-statistic, confidence interval and p-value are based on t distribution, so the most important is how to calculate the estimate and standard error. The pooled estimate is the mean value of all imputation's estimates. And the pooled SE is the square root of Vtotalthat can be ...
From there, a firm can calculate the unexpected operational loss within a certain confidence interval – which results in a calculation of the required capital to cover the risk and the required spread in the loans. But changing weather patterns and rising oceans are hard to...
