Normal Distribution

Normal Distribution and Standard Deviation of Stock Prices
A true Normal Distribution, also known as a Gaussian distribution, would produce a "bell-curve". An example of this is ploting the number of people of a certain height in a population.

Normal Distribution
Normal distribution describes data set that varies around an average value. See also: Market Profile, Standard Deviation

Normal Distribution
For the purposes of statistical testing, the simulated net returns are assumed to be drawn from a particular distribution.

Lognormal Distribution
A statistical distribution that is often applied to the movement of stock prices. It is a convenient and logical distribution because it implies that stock prices can theoretically rise forever but cannot fall below zero.

Lognormal distribution
Pattern of frequency of occurrence in which the logarithm of the variable follows a normal distribution. Lognormal distributions are used to describe returns calculated over periods of a year or more.

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.

Normal Distribution - a very important aspect of statistical analysis. All normal distributions are symmetric and have bell-shaped density curves with a single peak.

Normal Distribution: The normal distribution (a bell-shaped curve) represents a theoretical frequency distribution of measurements.

As the number of quotes for most banks is a relatively small number, usual time series models, based on the normal distribution, are not appropriate. Instead we work with time series models developed specifically for count data.

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.

In contrast to the often-assumed log-normal distribution of asset price returns, it is often observed that periods of high price volatility follow periods of low volatility and vice versa.

We believe that the basic normal distribution of market moves is based on random noise. Real trends exist, but they are hard to see through the noise. Leptokurtosis shows that there is something in the stock price other than noise.

The theory behind Bollinger Bands is that, in a normal distribution data set, 68% of data should fall within one standard deviation and that roughly 95% should fall within two standard deviations.

By definition, one standard deviation includes about 68% of all data points from the average in what is referred to as a normal distribution pattern, while two standard deviations include about 95% of all data points.

The chi-square test can be used to determine whether a sample of data comes from a normally distributed population by comparing its frequency distribution with that of the normal distribution.

The 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.

The variance-covariance technique for calculating VaR depends on the assumption that stock market returns are generally evenly distributed in a standard array known as the normal distribution curve; ...

Another striking feature of ProSticks is the Active Range. The Active Range is similar to the value area in Market Profile, such that it is derived from the normal distribution in statistical theory.

If you plot the results on a chart, you typically see the bell curve you may remember from high school (even though we don't like to remember where we were on the bell curve!). This is also referred to as the normal distribution curve.

The beauty of Monte Carlo Simulations is that they can be performed in a way that avoids the dangers of assumptions (such as that of the normal distribution) being violated, which would lead to untrustworthy results.

Stock prices and returns obey a normal distribution just like an unbiased coin thrown for heads and tails. The claims of technical analysis is then no more valid then the claims of astrology. This is what efficiency hypothesis says.
