In the standard deviation, the distances from the mean are squared, so large deviations are weighted more heavily, and thus outliers can heavily influence it. It is a robust statistic, being more resilient to outliers in a data set than the standard deviation. That is,Р’В starting with the residuals (deviations) from the dataРІР‚в„ўs median, the MAD is the median of their absolute values.Р”Р„s described in my previous post Standard Deviation, MAD is mostly used to overcome the outlier effect on sample population. It can also refer to the population parameter that is estimated by the MAD calculated from a sample.Р”Р‡or a univariate data set X 1, X 2,Р’В РІР‚В¦, X n, the MAD is defined as the median of the absolute deviations from the dataРІР‚в„ўsР’В median: In statistics, the median absolute deviation (MAD) is a robust measure of the variability of a univariate sample of quantitative data. Daily VaR for Gold calculated in Cell F16 is the product of the daily SMA volatility (Cell F18) and the z-value of the inverse of the standard normal CDF for 99.In EXCEL we calculate the inverse z-score at the 99 confidence level as NORMSINV (99) 2.326. Simple moving average (SMA) andР’В Exponential moving average (EMA) are the most popular type of Moving Average. They also form the building blocks for many other technical indicators and overlays, such as the McClellan OscillatorР’В and Bollinger Bands. Moving averages help smooth price action and filter out the noise.

Moving Average is used commonly for analyzing the short term fluctuations from a time series data and highlighting the long term trends.Р’В It can be easily seen in the above graph that the line MA(20) is smoothing out a lot of fluctuation as compared to the MA(10). Opportunities for successful security selection abounds when market dispersion is high, as discussed before. And the process is repeated over the entire data series.Р”Р‡ollowing graph depicts the Moving Average of Google Weekly closing price for 8 years for window size 10 & 20. Market dispersion refers to the variation in returns of the marketРІР‚в„ўs underlying securities. Then the subset is move forward by 1 element, removing the first element and adding the N+1 th element of the subset, and average is calculated for the 2 nd element of the Moving average. Given a data series and fixed subset size(N), the first element of Moving Average is obtained by averaging the initial fixed subset (first N elements) of number series. The standard deviation of return is the square root of the probability-weighted average of the square of the deviation of each possible return from expected return.

This is usually measured by another probability-based measure called standard deviation. So, just simply by going from one asset to two, from one bet to two bets in our betting portfolio, weve reduced the portfolio standard deviation from 100 to 71. First, we need to know the volatility of the returns of each asset class.

Now we have a little more variety in outcomes 0, 100, or 200.

In statistics, a Moving Average is used to analyze a set of data points by creating a series of averages of different subsets of the full data set. Well, the standard deviation in this case falls to 71.
