Usage

The Template:Infobox probability distribution generates a right-hand side infobox, based on the specified parameters. To use this template, copy the following code in your article and fill in as appropriate:

Parameters

|name= — Name at the top of the infobox; should be the name of the distribution without the word "distribution" in it, e.g. "Normal", "Exponential" (optional)
|type= — possible values are "discrete" (or "mass"), "continuous" (or "density"), and "multivariate"
|pdf_image= — probability density image-spec, such as: xxx.svg.
|pdf_caption= — probability density image caption
|pdf_image_alt= —
alternative text
for the image in |pdf_image=
|cdf_image= — cumulative distribution image-spec, such as: yyy.svg.
|cdf_caption= — cumulative distribution image caption
|cdf_image_alt= —
alternative text
for the image in |cdf_image=
|notation= — typical designation for this distribution, for example ${\mathcal {N}}(\mu ,\sigma ^{2})$ . The notation should include all the distribution parameters explained in the next cell.
|parameters= — parameters of the distribution family (such as $μ$ and $σ 2$ for the normal distribution).
|support= — the support of the distribution, which may depend on the parameters. Specify this as <math>x \in some set</math> for continuous distributions, and as <math>k \in some set</math> for discrete distributions.
|pdf= — probability density function (or probability mass function), such as: <math>\frac{\Gamma(r+k)}{k!\Gamma(r)}p^r(1-p)^k</math>. Please exclude the function label, such as " $ƒ (x; μ, σ 2)$ ".
|cdf= — cumulative distribution function, e.g.: <math>I_p(r,k+1)\text{ where }I_p(x,y)</math> is the [[regularized incomplete beta function]].
|quantile= — quantile function (or inverse cumulative distribution function). If $F()$ is the CDF and $Q()$ is the quantile function, then $Q(F(x))=x$
|mean= — the mean, or expected value.
|median= — the median, only for univariate distributions.
|mode= — the mode.
|variance= — variance of the distribution, or covariance matrix in multivariate case.
|mad= — the mean absolute deviation around the mean.
|skewness= — the skewness.
|kurtosis= — the
kurtosis excess
.
|entropy= — the differential
information entropy
, preferably expressed in unspecified units using base-unspecific log(.) rather than base-specific ln(.) which yields entropy in units of nats only.
|cross_entropy= — the cross-entropy of the model
|mgf= — the moment-generating function, for example: <math>\left(\frac{p}{1-(1-p) e^t}\right)^r</math>.
|char=/|cf= — the characteristic function, such as: <math>\left(\frac{p}{1-(1-p) e^{it}}\right)^r</math>.
|pgf= - the Probability-generating function.
|fisher= — the
Fisher information matrix
for the model.
|KLDiv= — the
Kullback-Leibler divergence
of the model
|JSDiv= — the
Jensen-Shannon divergence
of the model
|moments= — formulas to use in Method of moments for the model.
|ES= — the Expected shortfall or CVaR for the model.
|bPOE= — the Buffered Probability of Exceedance for the model.
|intro= — optional message which will be displayed before all other content in the infobox.
|marginleft= — margin space left of infobox (default: 1em).
|box_width= — width of the infobox (default: 325px).
