Calculate the skewness of a list along with its uncertainty
ResourceFunction["SkewnessAround"][{x1,x2,x3,…}] gives an Around object describing the skewness and corresponding uncertainty of the xi. |
Calculate the skewness of some numbers:
In[1]:= |
Out[1]= |
SkewnessAround works with symbolic expressions:
In[2]:= |
Out[2]= |
SkewnessAround also works with quantities with units, though the answer is dimensionless:
In[3]:= |
Out[4]= |
The skewness is independent of the units of course:
In[5]:= |
Out[5]= |
SkewnessAround applied to symbolic expressions can get unwieldy fast:
In[6]:= |
Out[6]= |
At least three value are needed to give a plausible error estimate:
In[7]:= |
Out[7]= |
Try with 3 values:
In[8]:= |
Out[8]= |
Skewness can give Indeterminate, in which case there will not be an Around result:
Study the skewness and its uncertainty for a sequence of values and compare it to the theoretical value of the distribution (dashed):
In[9]:= |
Out[13]= |
