#Stochastic

2025-10-14

This ebook introduces the fundamental elements of #stochastic processes, covering basic concepts, core knowledge, and essential methods.
=> 7 chapters including: foundations of probability, concepts of stochastic processes, Poisson processes, discrete-time Markov chains, continuous-time Markov chains, simple Markovian queueing models, and stationary processes. Each chapter features figures, examples, exercises,...

Another #Random #Stochastic #Walk added to my #R #Package #RandomWalker dev version, this time it is random_multinomial_walk(). As of now you can only generate a single trial but I'll work on it in the future, for now, let's just gt it into dev and move down the list.

I added another random walk to the dev version of my #R #Package #RandomWalker for the Wilcoxon Signed Rank using the #BaseR function rsignrank.

Take a look :)

Want to visualize 3D random walks? Then my #R package developed with my fellow R coder from another country Antti Rask called RandomWalker has you covered!

#R #RStats #RandomWalker #Random #Stochastic #plotly

library(RandomWalker)
library(plotly)

set.seed(123)
rw <- random_normal_drift_walk(.num_walks = 1, .dimensions = 3)

plot_ly(
  data = rw,
  x = ~ x, 
  y = ~ y,
  z = ~ z,
  type = "scatter3d",
  mode = "lines",
  opacity = 1,
  line = list(
    width = 1,
    color = "steelblue",
    reverscale = FALSE
  ))library(RandomWalker)

If you don't have at least a bit of contextual knowledge of any subject you ask AI about, you will be pawned. You will be pawned by AI hard. The usual stochastic parrot text generation looks like this:
Question
AI: Answer
Is that small part correct?
AI: Oh, you are right about that.
Further question
AI: Further Answer
What about the small detail, shouldn't it be like ... ?
AI: You are absolutely correct, let's change it so...

I saw this book on another post - and so went and found a copy at a 2nd hand book shop…
Looking forward to lunches at work with a cup of tea and maybe a couple of rainy Sundays at home…

Nabeel et al. present a method to derive models of theoretical ecology from stochastic time series data. This data-driven method may help empirical tests of ecological theories and to discover unknown principles. Read now ahead of print!

Ah, right. I suspect the Felon-in-Chief's stochastic terrorism is responsible for that. Public figures don't want the abuse-and-threats firehose turned on them.

Okay, terrible, sure, but if we save all that text I'm pretty sure we can predict the future, but only if our hearts are pure. #Microsoft is fighting a fierce battle behind the scenes against the spirit of Prophecy, which has just won a major victory.

Of course, like channelers of prognostication in ancient Greece, Microsoft is also mentally ill to the point of losing contact with all external reality. Such is the case with oracles 🤷
