Probability in Statistics

Probability in Statistics

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...

Determination of Expected Frequency

Determination of Expected Frequency

Suppose one wants to test independence between the two variables of a contingency table. The values in the table constitute the observed frequencies of the dataset. But how does one determine the expected frequency of the dataset? One of the important assumptions is that the two variables are independent, which means the variables do not influence each other. For independent variables, the statistical probability of any event involving both variables is calculated by multiplying the individual...

Probability Histograms

Probability Histograms

A probability histogram is a visual representation of a probability distribution. Similar a typical histogram, the probability histogram consists of contiguous (adjoining) boxes. It has both a horizontal axis and a vertical axis. The horizontal axis is labeled with what the data represents. The vertical axis is labeled with probability. Each rectangular bar in the histogram is 1 unit wide, which suggests that the area under each bar equals the probability, P(x), where x is 1, 2, 3, and so on.

Binomial Probability Distribution

Binomial Probability Distribution

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,...

Introduction to Test of Independence

Introduction to Test of Independence

In statistics, the term independence means that one can directly obtain the probability of any event involving both variables by multiplying their individual probabilities. Tests of independence are chi-square tests involving the use of a contingency table of observed (data) values.
The test statistic for a test of independence is similar to that of a goodness-of-fit test:

Unusual Results

Unusual Results

Unusual results are those that have a very low chance of occurring. Unusual results can be identified using probabilities and the range rule of thumb. In problems involving probability, unusual results can be observed in 2 instances – an unusually high number of successes or an unusually low number of successes.
According to the range rule of thumb, any value above or below two standard deviations, 2σ from the mean, μ is considered unusual.
Maximum unusual value = μ + 2σ
Minimum unusual value...

Background:

Order statistics are crucial for analyzing data from multiple sources.
Understanding the distribution of samples from different populations is essential for comparative analysis.
The Benjamini-Hochberg procedure is widely used for controlling false discoveries in hypothesis testing.

Purpose of the Study:

To derive a probability distribution for order statistics from two distinct populations.
To establish a method for calculating probabilities of order statistics falling into specified disjoint intervals.

Main Methods:

Developing a probability model for order statistics from two independent populations with potentially different distribution functions.
Deriving formulas for the joint probability of order statistics falling within ordered, disjoint intervals.
Utilizing the derived probabilities to compute the joint probability of rejections and false rejections in the Benjamini-Hochberg procedure.

Main Results:

A general formula is presented for the probability of order statistics from two populations falling into disjoint intervals.
The probability of a specific number of the smallest order statistics originating from the first population is determined.
The application to the Benjamini-Hochberg procedure yields a method for calculating joint probabilities of interest.

Conclusions:

The derived probability framework offers a novel approach to analyzing order statistics from mixed populations.
This method provides a robust tool for evaluating the performance of the Benjamini-Hochberg procedure.
The findings have implications for statistical inference and hypothesis testing in scenarios involving multiple data sources.
