Why should we learn probability and stochastic processes?
Stochastic processes underlie many ideas in statistics such as time series, markov chains, markov processes, bayesian estimation algorithms (e.g., Metropolis-Hastings) etc. Thus, a study of stochastic processes will be useful in two ways: Enable you to develop models for situations of interest to you.
What is stochastic in probability?
In probability theory and related fields, a stochastic (/stoʊˈkæstɪk/) or random process is a mathematical object usually defined as a family of random variables. Stochastic processes are widely used as mathematical models of systems and phenomena that appear to vary in a random manner.
How do you make a stochastic process model?
The basic steps to build a stochastic model are:
- Create the sample space (Ω) — a list of all possible outcomes,
- Assign probabilities to sample space elements,
- Identify the events of interest,
- Calculate the probabilities for the events of interest.

What is a valid stochastic process?
A stochastic process means that one has a system for which there are observations at certain times, and that the outcome, that is, the observed value at each time is a random variable.
What is the importance of stochastic process?
Since stochastic processes provides a method of quantitative study through the mathematical model, it plays an important role in the modern discipline or operations research.
