 ResourceFunction["ArcsineLawRandomnessTest"][sequence] uses the arcsine law to test sequence for randomness and returns an associated p-value. ResourceFunction["ArcsineLawRandomnessTest"][sequence,"property"] tests sequence for randomness and returns the specified property.

## Details and Options

Properties include:
 "TestStatistic" returns the test statistic "PValue" returns the p-value associated with the test
The test works only for sequences of zeros and ones.
ResourceFunction["ArcsineLawRandomnessTest"] results are generally invalid for sequence lengths shorter than 100.
The test returns a two-tailed p-value.

## Examples

### Basic Examples (3)

Generate a sequence of random integers:

 In[1]:=

Visualize the sequence:

 In[2]:=
 Out[2]=

Apply a runs-based test:

 In[3]:=
 Out[3]=
 In[4]:=
 Out[4]=

### Applications (2)

Generate a sequence of random integers:

 In[5]:=

Visualize the sequence:

 In[6]:=
 In[7]:=
 Out[7]=

Attempt to reject a non-random sequence:

 In[8]:=
 Out[8]=
 In[9]:=
 Out[9]=

Test the randomness of rule 30:

 In[10]:=
 In[11]:=
 Out[11]=
 In[12]:=
 Out[12]=

### Possible Issues (1)

ArcsineLawRandomnessTest requires sequences of length 100 or more:

 In[13]:=

### Neat Examples (1)

Visualize the sampling distribution of the test statistic:

 In[14]:=
 In[15]:=
 Out[15]=
