Access and Manipulate Curated Custom Entities

Import an entity store with data about univariate probability distributions.

In[1]:=

es = CloudGet@CloudObject[ "https://www.wolframcloud.com/objects/user-8a7d28b9-c01d-46b8-ba65-\ c3daa0ded865/ProbabilityDistribution-EntityStore"]

Out[1]=

Set it as one of the entity stores automatically accessed by the Entity framework.

In[2]:=

$EntityStores = {es};

There are 465 probability distributions in this store.

In[3]:=

EntityValue["ProbabilityDistribution", "EntityCount"]

Out[3]=

And there are up to 67 properties per distribution.

In[4]:=

EntityValue["ProbabilityDistribution", "PropertyCount"]

Out[4]=

This is the data available for the normal distribution.

In[5]:=

EntityProperty["ProbabilityDistribution", "SamplePlottingParameters"]

Out[5]=

In[6]:=

data = Normal[ EntityValue[Entity["ProbabilityDistribution", "Normal"], "PropertyAssociation"]]; data = DeleteCases[data, EntityProperty["ProbabilityDistribution", "SamplePlottingParameters"] -> _]; data = data //. HoldPattern[Function[a_, b_]] :> b //. HoldPattern[Inactive[ConditionalExpression][a_, b_]] :> Row[{a, Style[" for ", Gray], b}]; data = Activate[data, Sqrt | DirectedInfinity | Piecewise | _Derivative]; Grid[List @@@ data, Alignment -> Left, Dividers -> All, Background -> {None, {{LightGray, White}}}] // TraditionalForm

Out[6]//TraditionalForm=
