### Testing underlying, latent normality of binary data

I have two multivariate binary datasets of 4 variables (or components) - P, Q, R and S each. Each row of the data is like a test on the components to say if they work (0) or fail (1) when tested. The ...

### Marginal effect of binary choice model

Suppose we have a standard binary choice model. However, the regressors $x$ are partitioned into two parts: $x = (x, d)$, where $X_1\in R^k$ and $d\in(0,1)$. $\beta = (\beta_1, \beta_2)$ are ...

### Using -1 instead of 0 in binary Restricted Boltzmann Machines

I am aware of the fact that binary Restricted Boltzmann Machines - which use $0$ or $1$ as states - are asymmetric, in the sense that two states have to be both $1$ for $w_{ij}$ to enter in the energy ...
