Examples of Bayes' factor in the following topics:
-
- In probability theory and statistics, Bayes' theorem (or Bayes' rule ) is a result that is of importance in the mathematical manipulation of conditional probabilities.
- The relationship is expressed in terms of the likelihood ratio, or Bayes' factor.
- More specifically, given events $A_1$, $A_2$ and $B$, Bayes' rule states that the conditional odds of $A_1:A_2$ given $B$ are equal to the marginal odds $A_1:A_2$ multiplied by the Bayes factor or likelihood ratio.
- Rationally, Bayes' rule makes a great deal of sense.
- Furthermore, Bayes' rule can be applied iteratively.
-
- In these cases, we can apply a very useful and general formula: Bayes' Theorem.
- Bayes' Theorem states that this conditional probability can be identified as the following fraction:
- Bayes' Theorem is just a generalization of what we have done using tree diagrams.
- Use Bayes' Theorem only when there are so many scenarios that drawing a tree diagram would be complex.
- Here we solve the same problem presented in Exercise 2.57, except this time we use Bayes' Theorem.
-
- In probability theory and statistics, Bayes' theorem (alternatively Bayes' law or Bayes' rule) is a result that is of importance in the mathematical manipulation of conditional probabilities.
- Mathematically, Bayes' theorem gives the relationship between the probabilities of $A$ and $B$, $P(A)$ and $P(B)$, and the conditional probabilities of $A$ given $B$ and $B$ given $A$.
-
- Compute the probability of a condition from hits, false alarms, and base rates using Bayes' Theorem
- This same result can be obtained using Bayes' theorem.
- Bayes' theorem considers both the prior probability of an event and the diagnostic value of a test to determine the posterior probability of the event.
- Bayes' theorem shown below allows you to calculate P(D|T), the probability that you have the disease given that you test positive for it.

- Bitter religious conflicts contributed to hostility toward foreign Christians and Europeans, which persisted into the 20th century and were a factor in Ethiopia's isolation until the mid-19th century, when the first British mission, sent in 1805 to conclude an alliance with Ethiopia and obtain a port on the Red Sea in case France conquered Egypt.

- Bayes' theorem considers both the prior probability of an event and the diagnostic value of a test to determine the posterior probability of the event.
- For example, if the factor were drug dosage, and three doses were tested, then each dosage would be one level of the factor and the factor would have three levels.
- In a design with two factors, the marginal means for one factor are the means for that factor averaged across all levels of the other factor.
- Also called a "repeated measures factor. "
- The simple effect of a factor is the effect of that factor at a single level of another factor.
-
- This is a complete list of the factors of 24.
- Therefore, 2 and 3 are prime factors of 6.
- However, 6 is not a prime factor.
- To factor larger numbers, it can be helpful to draw a factor tree.
- This factor tree shows the factorization of 864.
-
- Factoring by grouping divides the terms in a polynomial into groups, which can be factored using the greatest common factor.
- Factor out the greatest common factor, $4x(x+5) + 3y(x+5)$.
- Factor out binomial $(x+5)(4x+3y)$.
- One way to factor polynomials is factoring by grouping.
- Both groups share the same factor $(x+5)$, so the polynomial is factored as
-
- Sigma factors are proteins that function in transcription initiation .
- The activity of sigma factors within a cell is controlled in numerous ways.
- However, if transcription of genes is not required, sigma factors will not be active.
- The anti-sigma factors will bind to the RNA polymerase and prevent its binding to sigma factors present at the promoter site.
- The anti-sigma factors are responsible for regulating inhibition of transcriptional activity in organisms that require sigma factor for proper transcription initiation.

- By the first decades of the 18th century, the French created and controlled such colonies as Quebec, La Baye des Puants (present-day Green Bay), Ville-Marie (Montreal), Fort Pontchartrain du Détroit (modern-day Detroit), or La Nouvelle Orléans (New Orleans) and Baton Rouge.
