normal distribution
probability distribution. It has the following important characteristics: (1) the curve has a single peak; (2) it is bell-shaped; (3) the mean (average) lies at the center of the distribution, ...

Normal distribution
Definition: Normal distributions are important for a number of reasons. One of the main ones is that many of the important characteristics that you will want to study are normally distributed.

normal distribution Perhaps the most important probability distribution for probability and statistics.
quantile A notion from probability that can be used as a parameter.

Normal distribution
The most widely occurring frequency distribution. The normal distribution is characterised by its symmetrical bell shape. The mean indicates the position of the centre of the bell, the standard deviation how spread out it is.

Normal distribution curve - A graphical representation of the normal distribution.
Normal good - A good (or service) for which demand increases as income increases.

Normal Distribution
The well known bell shaped curve. According to the Central Limit Theorem, the probability density function of a large number of independent, identically distributed random numbers will approach the normal distribution.

Lognormal distribution
A distribution where the logarithm of the variable follows a normal distribution.
lognormal distributions are used to describe returns calculated over periods of a year or more.

Lognormal Distribution
The standard statistical model for the expected distribution of asset price movements. More technically, it assumes that the natural logarithms of relative price movements are normally distributed.

Normal distribution A forming a symmetrical bell-shaped curve.
Normal portfolio A customized that includes all the securities from which a manager normally chooses, weighted as the manager would weight them in a .

Normal Distribution - Is one of the most popular and well documented probability distributions. It is frequently depicted as the bell-shaped curve. This process underlies much of financial theory and practice.

Normal distribution/curve
A symmetrical bell-shaped statistical distribution where most of the examples in a set of data are close to the mean or “average' while relatively few examples tend to be one extreme or the other.

Standardized normal distribution
A normal distribution with a mean of 0 and a standard deviation of 1.

Not using the normal distribution also means that the distributions used can reflect other properties of real life returns such as fat tails.

A statistical technique for fitting a curve to a set of data points. One of the variables is transformed by taking its logarithm, and then a straight line is fitted to the transformed set of data points.

Central Limit TheoremThe Law of Large Numbers states that as a sample of independent, identically distributed random numbers approaches infinity, its probability density function approaches the normal distribution. See: Normal Distribution.

Leptokurtosis The condition of a probability density curve to have fatter tails and a higher peak at the mean than the normal distribution. Less-developed countries (LDCs) Also known as emerging markets.

The normal distribution assumes continuous changes in a system. However, a time series which exhibits Hurst statistics may abruptly change levels, skipping values either up or down.

As a result, large swings (3 to 6 standard deviations from the mean) occur in the market more frequently than the normal distribution assumption would expect. [2]
The model assumes that the variance of returns is an adequate measurement of risk.

It is sometimes adjusted to put the kurtosis of a normal distribution at zero (although some mathematicians then call it "excess kurtosis").

For instance, the height of six-year-olds may come close to forming a normal distribution around its mean (or average) value.

In other words, Kurtosis measures whether the data is sharp or flat relative to a normal distribution. Since Kurtosis measures the shape of the distribution (the fatness of the tails), it focuses on how returns are ranged around the mean.

The IID (o,σ2) implies that the variation of εt is with 0 mean and σ2 (if we assume a normal distribution of εt, the equation is an arithmetic Brownian motion observed at regular unitary intervals of regular length).

A type of probability distribution that is theoretical and resembles a normal distribution. A T distribution differs from the normal distribution by its degrees of freedom.

N(d) = the probability that a random draw from a standard normal distribution will be less than (d).

If a fund's returns follow a normal distribution, then approximately 68% of the time they will fall within one standard deviation of the mean return for the fund, and 95% of the time within two standard deviations.

A distribution where the logarithm of the variable follows a normal distribution. Lognormal distributions are used to describe returns calculated over periods of a year or more.

The Bell curve distribution is a common name given to a normal distribution. This states that for many variable occurences, results tend to be centred on the average, at either extremes of the average the distribution sharply falls.

For a normal distribution, boundaries set at two standard deviations from the mean create approximately 95 percent confidence intervals. In other words, only 5 percent of the events will be smaller or larger than the boundary amounts.

Kurtosis measures the fatness of the tails of the distribution. Excess kurtosis means that distribution has fatter tails than normal distribution.
