... in mean CRP was between 1.21 and 2.70 mg/L higher in patients who die within 4 years. This difference is statistically significant with a p-value < 0.0001 and thus we can state with high confidence that the mean CRP level is higher in patients who have a higher likelihood of death within a 4 year pe ...

Multiple Regression - Berkeley Statistics

It was the hope of accounting for some of that leftover variability that led us to try a second predictor. The standard deviation of the residuals is still denoted s (or somet ...

It can only indicate how or to what extent variables are associated with each other. Any conclusions about cause and effect must be based upon the judgment of those individ ...

Using Interviewer Random Effects to Calculate Unbiased HIV

In this case, we use interviewer identity, zj , as the selection variable, as it is plausibly unrelated to HIV status. Interviewe ...

The optimum yield of capsaicinoids of 16.48 mg/g was obtained using 0.5 g sample with 20 ml of 80% (v/v) methanol in water at 50oC for 20 min. The analytical figures of merit were validated and ap ...

We show that the DBS has same properties as the UBS, only the conditions on the weights are different. We show that all the known jackknife schemes belong either to UBS or DBS. I ...
