distr_chi2 function

Creates a Chi2 distribution parameterized by shape parameter df. This is exactly equivalent to distr_gamma(alpha=0.5*df, beta=0.5)

distr_chi2(df, validate_args = NULL)

Arguments

• df: (float or torch_tensor): shape parameter of the distribution
• validate_args: whether to validate arguments or not.

Examples

if (torch_is_installed()) {
m <- distr_chi2(torch_tensor(1.0))
m$sample() # Chi2 distributed with shape df=1
torch_tensor(0.1046)
}
