- Teoría de la decisión
Sus antecedentes:
- La estimación estadística de las probabilidades es desafiada por la incertidumbre y los valores desconocidos.
- Los métodos existentes pueden carecer de robustez cuando se trata de información probabilística imprecisa.
Objetivo del estudio:
- Proponer un nuevo concepto de robustez basado en probabilidades de valor fijo.
- Proporcionar un marco unificado y versátil para la estimación estadística bajo incertidumbre.
- Para obtener condiciones óptimas de convexidad y estabilidad para una mayor robustez.
Principales métodos:
- Utilizando el marco de probabilidades de valor fijo.
- Empleando técnicas de escalarización para probabilidades de valores fijos.
- Derivar las condiciones óptimas y establecer las propiedades generalizadas de convexidad y estabilidad.
Principales resultados:
- Un nuevo concepto unificado de robustez para la estimación probabilística.
- Optimalidad, convexidad generalizada y condiciones de estabilidad derivadas de la escalarización.
- Aplicabilidad demostrada en la gestión de carteras financieras y en la teoría de la medida del riesgo.
Conclusiones:

Probability is the likelihood of an event occurring. The term event is defined as a collection of results of a procedure. An event is a simple event when an outcome cannot be divided into simpler parts.
An example of a simple event is a coin toss. The result of a coin toss is either a head or a tail. Here, head and tail are two simple events. These two simple events make up the sample space. Further, the probability of an event occurring falls within the range of 0 to 1. The probability of an...

Probability Distributions

The probability of a random variable x is the likelihood of its occurrence. A probability distribution represents the probabilities of a random variable using a formula, graph, or table. There are two types of probability distribution– discrete probability distribution and continuous probability distribution.
A discrete probability distribution is a probability distribution of discrete random variables. It can be categorized into binomial probability distribution and Poisson...

Random Variables

A random variable is a single numerical value that indicates the outcome of a procedure. The concept of random variables is fundamental to the probability theory and was introduced by a Russian mathematician, Pafnuty Chebyshev, in the mid-nineteenth century.
Uppercase letters such as X or Y denote a random variable. Lowercase letters like x or y denote the value of a random variable. If X is a random variable, then X is written in words, and x is given as a number.
For example, let X = the...

Randomized Experiments
7.2K
The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.

Binomial Probability Distribution
11.4K
A binomial distribution is a probability distribution for a procedure with a fixed number of trials, where each trial can have only two outcomes.
The outcomes of a binomial experiment fit a binomial probability distribution. A statistical experiment can be classified as a binomial experiment if the following conditions are met:
There are a fixed number of trials. Think of trials as repetitions of an experiment. The letter n denotes the number of trials.
There are only two possible outcomes,...
