Canonical correlation analysis (CCA) determines a set of canonical variates, orthogonal linear combinations of the variables within each set that best explain the variability both within and between sets. It is used to identify and measure the associations among two sets of variables. How to perform canonical correlation analysis in R? Follow this step to find canonical … Read more
Mean is the central value of all the observation which are included in a study. There are various types of mean exist. They are arithmetic mean, geometric mean, harmonic mean etc. Definiton The arithmetic mean of a set of data maybe defined as the sum of the values divided by the number of values in … Read more
Measures of central tendency are numerical indices of statistical data that are generally indicative of the center, middle or representative of a data set. Understanding data is crucial in statistics, business, and research. One of the fundamental concepts in data analysis is measures of central tendency, which help summarize a dataset with a single representative … Read more
In today’s data-driven world, statistical data plays a crucial role in decision-making across industries. Whether in business, healthcare, finance, or research, statistics help analyze trends, make predictions, and improve efficiency. Understanding statistical data is essential for anyone looking to interpret numerical information accurately. This article explores the fundamentals of statistical data, its types, and practical … Read more
In probabilistic statistics, the gamma distribution is a two-parameter family of continuous probability distributions which is widely used in different sectors. The exponential distribution, Erlang distribution, and chi-square distribution are special cases of it. PDF of Gamma Distribution A continuous random variable X is said to have a generalized gamma distribution with parameter α … Read more
In probabilistic statistics, the exponential distribution is the probability distribution of the time between events in a Poisson point process where events occur continuously and independently at a constant average rate. It is a special case of the gamma distribution. The exponential distribution is frequently used to calculate the amount of time until a certain … Read more
Uniform distribution is a fundamental concept in probability theory and statistics. It represents a scenario where all outcomes are equally likely, making it an essential tool in data analysis, simulations, and real-world applications. It is used in statistics to describe a type of probability distribution in which every conceivable outcome has an equal chance of … Read more
A power series distribution is a discrete probability distribution that applies to a subset of natural numbers. The distribution’s names derive from the fact that the power series is used to construct them. This broad category of distributions includes a number of discrete distributions, such as the Poisson distribution, negative binomial distribution, and binomial distribution. … Read more
The logarithmic series distribution is a discrete probability distribution obtained from the Maclaurin series expansion. Sometimes it is known as log-series distribution. It has a long right tail with one parameter, which ranges from 0 to 1. This distribution models a wide range of events, including data on animal diversity and the frequency of insurance … Read more
