    I have a large distribution of paired percentages. Is there a best way, or any way, to test for sig. different pairs?

    These percentages are based on RNA sequencing count data for which replicate values have been merged and transformed to these percentages (which represent average lengths, not counts). But since the replicate data has been lost in the transformation to %, I'm not sure if I can still test for...

    Why three-way ANOVA doesn't match with multiple comparisons?

    Hi, I'm running a three-way ANOVA on a multifactorial dataset and it says all three (Device, HRT, Dose) variable has a significant influence on the data. However, when I run multiple comparisons, groupings and significance appear only based on one of the variables (Dose). Why is that and which...

    Generalisation of 'overlapping confidence intervals'

    I had a question about a common (possibly incorrect) trend in the medical field to look at whether two 95% confidence intervals overlap as a sign of statistical significance at the 95% level. I'm aware this is overly conservative. I've heard that 83% confidence intervals are 'better' but not...

    Beta significance level in one model the same as the R-squared-change significance

    I am very new to statistics, so apologies in advance if I have not explained this clearly. I have run two types of linear regression: - The first contains 4 independent variables, all entered at the same time. - The second uses "blocks" to enter 3 of the independent variables in the first...
