If Mean Absolute Deviation(MAD) = 2 for the four periods under consideration, what is the forecast for period 4? What is the 95% prediction interval for Y when X1 is equal to 40 (in 000's)? What is time series forecasting? Give an example. Consider the follow...

The median absolute deviation is defined as: mad(x)=1.4826 \cdot median(|x_i-median(x)|). This is a resistant measure of spread and is implemented in the mad () function. Explain in words what it measures. Compare the values of the sample standard dev ...

They are two versions of mean squared error (MSE) and mean absolute deviation (MAD), given by the following: where ς̂ t+1 is the true volatility and ĥ (t+1∣t) is the one-step ahead volatility forecast made at time t. For in-sample results, the estimation period is from ...
For symmetric distributions, where the median is equal to the midhinge (the average of the first and third quartiles), the IQR has another interesting property. In such cases, half of the IQR is equivalent to the Median Absolute Deviation (MAD), a robust measure of dispersion. The IQR’s...
An interview with the author of a new book about the Northeast Corridor reminded me of this; this is not the focus of the interview, but there was an invocation of incremental vs. full-fat high-speed rail, which doesn’t really mean much. The problem is that the debate over ...
A high variance indicates thatthe data points are very spread out from the mean, and from one another. Variance is the average of the squared distances from each point to the mean. The process of finding the variance is very similar to finding the MAD, mean absolute deviation. ...
Blink-182 are one of the most beloved bands of the last 30 years, and were a major pillar in the foundation of the pop-punk genre. But which of their albums is the best? That's what we want to know during this week's Loudwire Nights Album of the Week poll. You'll have until ...
So consider-others-above-yourself, altruistic, UNCONDITIONAL SELFLESSNESS is the underlying theme of existence. It’s the glue that holds the world together, and it is, in fact, what we mean by the term ‘love’. Indeed, if we consider religious terminology, the old Christian word for ...
