👉 In statistics, a log-normal distribution is a continuous probability distribution that arises naturally in many applications. It can be described as follows: - The mean of the distribution is equal to 0. - The standard deviation of the distribution is equal to 1. A log-normal distribution has two parameters: the scale parameter (σ) and the shift parameter (μ). The scale parameter σ determines how much the mean of the distribution varies from one observation to another. For example, if σ is equal to

What is the definition of Lognormally? 🙋
👉 Lognormal distribution is a family of continuous probability distributions that are characterized by two parameters: the location parameter $\mu$ and the scale parameter $\sigma$. It is a special case of the normal distribution with the additional property that the mean of the distribution equals zero, and its standard deviation is equal to one. The lognormal distribution can be used for modeling various phenomena such as weather patterns, stock prices, and financial returns.
The lognormal distribution has several key properties:

What is the definition of Lognormality? 🙋
👉 Lognormality refers to a family of probability distributions that arise in many fields, including finance and engineering. The lognormal distribution is one such family of probability distributions, characterized by its bell-shaped curve with tails that are approximately normal but tapering towards zero. Lognormal distributions have been studied extensively for their ability to model complex financial market phenomena such as interest rates, stock prices, and exchange rate movements.
