Method Details

init(self, mu, sigma)
(Constructor)

source code

x.__init__(...) initializes x; see help(type(x)) for signature

Parameters:

sigma (float) - The standard deviation of the log of the resulting distribution.
mu (float) - The median of the resulting distribution, not the log of the median.

Raises:

ValueError - Bad parameters for the distribution.

Overrides: object.__init__

call(self)
(Call operator)

source code

Sample from the probability distribution.

Returns: float: the sample
Overrides: probdist_c.__call__: (inherited documentation)

logdens(self, x)

source code

Return the log(density) of the probability distribution at x.

Parameters:

x - the position where the density should be evaluated.

Returns: float

log(density)

Raises:

mcmc.NotGoodPosition - when the density is not defined at x.

Overrides: probdist_c.logdens
