Functions

func LogDSigm added in v0.10.1

func LogDSigm(x float64) float64

LogDSigm is log d Sigm(x) / dx, used for computing log probability in the presence of sigmoid-transformed variables.

func LogGamma

func LogGamma(x float64) float64

LogGamma is used in the log-density of the Gamma and Beta distributions.

func LogSumExp

func LogSumExp(x, y float64) float64

LogSumExp computes log(exp(x) + exp(y)) robustly.

func Sigm

func Sigm(x float64) float64

Sigmoid computes the sigmoid function 1/(1 + exp(-x)).
