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:

|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 . The notation should include all the distribution parameters explained in the next cell.|parameters=
— parameters of the distribution family (such as μ and σ2 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,σ2)".|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 is the CDF and is the quantile function, then |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).|parameters2=

are the same as their counterparts above. They should be used when the distribution needs two sets to describe it, e.g. Gamma distribution.
