We propose a latent variable model for mixed discrete and continuous outcomes. The model accommodates any mixture of outcomes from an exponential family and allows for arbitrary covariate effects, as ...

The maximum likelihood (ML) procedure is used to estimate the correlation between a discrete and a continuous variable. The discrete variable is assumed to be a classification of an unobservable ...

Classifying a variable as a particular type of data is important when considering how to present the data. Data can be presented in a number of ways, which depends on the type of variable and the uses ...

An optical discrete time-frequency domain transform technology is proposed for ultra-fast optical waveform measurements. By using the technology, single shot ultrafast optical phenomena in a long time ...
