### Inference on bootstrapped-confidence interval resulting in multimodal distribution

I have a set of paired data that I am using to calculate a ratio. The ratio is calculated as the sum of column 2 over the sum of column 1 (please see below) ...

### Estimating population size of a subgroup based on independent samples without replacement

Let a bag have 1000 balls, 100 red and 900 blue. Now, let us get ten independent samples (without replacement within each sample) of the original population (10% each). Proceed to count the number of ...

### Computing confidence Intervals of ratio of correlated variables

Say I have $n$ independent observation of two random variables $x$ and $y$, which may be correlated, and I want to estimate $r=E[x/y]$. I can use $\bar{r}=\sum_i \frac{x_i}{y_i}$ to estimate $r$ but ...

### If I reject the null on a two sample t-test, can I conclude which direction the difference goes?

Since it's a two-sided test, it seems plausible that I can only reject that the difference is 0. However, if the entire interval is negative or positive can I say that one is larger or smaller than ...

### A non-statistician reference for confidence-interval Vs credibility-interval interpretation

As a beginner statistician, discussing the need to be accurate with the interpretation of statistical results with non-statistician is not an easy task. In particular, I am trying to convince some ...
I would like to compute belief intervals (confidence intervals; CI) for the parameters of an environmental dynamic model within the Bayes' theorem. The measurement model of the data is  ...
