tfd_cholesky_lkj {tfprobability}

The CholeskyLKJ distribution on cholesky factors of correlation matrices

Description

This is a one-parameter family of distributions on cholesky factors of correlation matrices. In other words, if If X ~ CholeskyLKJ(c), then X @ X^T ~ LKJ(c). For more details on the LKJ distribution, see tfd_lkj.

Usage

tfd_cholesky_lkj(
  dimension,
  concentration,
  validate_args = FALSE,
  allow_nan_stats = TRUE,
  name = "CholeskyLKJ"
)

Arguments

dimension

integer. The dimension of the correlation matrices to sample.

concentration

float or double Tensor. The positive concentration parameter of the CholeskyLKJ distributions.

validate_args

Logical, default FALSE. When TRUE distribution parameters are checked for validity despite possibly degrading runtime performance. When FALSE invalid inputs may silently render incorrect outputs. Default value: FALSE.

allow_nan_stats

Logical, default TRUE. When TRUE, statistics (e.g., mean, mode, variance) use the value NaN to indicate the result is undefined. When FALSE, an exception is raised if one or more of the statistic's batch members are undefined.

name

name prefixed to Ops created by this class.

Value

a distribution instance.
