### Is there a standard measurement of 2-dimensional precision?

Suppose a gun is fired at the bullseye of a target a specific number of times. Ignoring the accuracy (e.g. all the shots are well to the left and above the bullseye), is there a standard way of ...

### Bias results for mismeasurement of continuous confounders

Consider data generated from a model $Y = \alpha A + \beta U$, where $U$ is a confounder, i.e. $\langle A,U\rangle \neq 0$. We don't measure U, but rather a noisy version of it, $U' = U+\epsilon$, ...

### Estimate how many wrong measures there is in a sample

This study shows that the average penis mean is 13.24cm and the standard deviation is 1.89cm. Let's suppose we have a population with this mean and standard deviation for penis length. Suppose we ask ...

### Bayesian inference for simple gaussian model with measurement error

I'm having trouble understanding how to specify a model for Bayesian inference. I have a set of measurements, each with known uncertainty, and I would like to infer the mean of the measurements with ...

### How to model discretised values of a continuous variable?

I have some measurements--tissue swelling in response to an injury--with limited precision (mm). Thus, although the underlying phenomenon is continuous, my values are discrete. The values range ...
