It is not that there are drawbacks to k-means, but rather there are drawbacks to implementations that ignore multiplicity. Part of this is due to the influence of of older k-neighbor algorithms, designed for compiler construction in a single threaded...
Thank you Kuba for your quick reply plus examples. So "& @" now makes sense, a prefixed pure function. NumberForm is a good idea too -- it gets to the heart of what I wanted. Quantity[] is also desirable, but upon export in tabular form does not...
"I would say PT is the geographic region that switches between PST and PDT". The actual definition has PDT as a zone to accommodate portions of PST that do/did/will not change during the year. But I endorse the idea returning a value other than a...
Thanks Jim for demonstrating MovingAverage and TimeSeriesModel. You saved me from implementing my own window code. Was 49 a whim or? I could tune it based on variance response.
Isn't W|A input the same as cntl+= in the desktop version? That's what I've done above.
Jeff, thanks for keeping us posted on this. According to the prediction above they would pass within 10 miles. It sure beats 10 feet!
That was very good advice.
Mahmudul, The Manhattan distance is a built-in function with Mathematica: https://reference.wolfram.com/language/ref/ManhattanDistance.html?q=ManhattanDistance There is a guide to Series in Mathematica here:...
Murat, you are referring to the subject of Numerical Analysis as "Optimized Simulation". In my opinion this is an equivocation.
m is a parameter of the expression. Whether it is integer or real has no impact on the solution. The sum looks familiar from decades ago. I've no recollection though of where it arises.
