| Thank you all for pointing out the issues! As for the formulas: Variance of a sample has different scaling factor, hence the difference. Use the second CentralMoment instead: ``` In[175]:= data = {1, 2, 3}; In[176]:= wd = WeightedData[data,... |
| Hi Dave, thank you for sharing! That's a great expansion of my post and it is so curious to find that so many subdivisions duplicate the name of the state they are in. |

| You can do: ``` In[24]:= RipleyK[{proc4, Entity["Country", "France"]}, Range[0, 10, 1]] Out[24]= {Quantity[0., ("Miles")^2], Quantity[0., ("Miles")^2], Quantity[0., ("Miles")^2], Quantity[0., ("Miles")^2], Quantity[0., ("Miles")^2],... |
| Unfortunately has not been resolved yet... |
| None of the countries bordering Poland before 1990 exist today: the fall of the Berlin Wall and USSR just like people - even in the border-stable countries :) |
| Thank you for your suggestion - it is good to know that there is interest in the spatial interpolation methods. |
| If you want to average over realizations you need to first simulate multiple paths. `CorrelationFunction` for ensemble of paths will automatically take average: ``` proc = TransformedProcess[E^(I*b[t]), b \[Distributed] WienerProcess[], t]; ... |
| Time series approach: series1 = Table[{i, y1[i]}, {i, 1, 10}]; series2 = Table[{i, y2[i]}, {i, 1, 10}]; series3 = Table[{i, y3[i]}, {i, 1, 10}]; Create multivariate TemporalData with y's component and x's as times: td =... |
