or trading volumes. Moving averages are used to eliminate short-term fluctations in time series and highlight long-term trends and cycles. The threshold between short-term and long-term depends on the application, and the parameters of the moving average will be set accordingly. A simple moving average is the unwieghted mean of the previous n data points in the time series.

that is, exhibits no discernable trend or seasonality and is subject only to the randomness of everyday existence, then moving average methods – or even a simple average of the entire series – are useful for forecasting the next few periods. However, most time series are anything but stationary: retail sales have trend, seasonal, and cyclical elements, while public utilities have trend and seasonal components that impact the usage of electricity and heat. Hence, moving average forecasting approaches may provide less than desirable results. Moreover, the most recent sales figures typically are more indicative of future sales, ... market research, surveys and trends

China's housing bubble myth
Today I am going to try and burst the most subtle and insidious bubble of them all: the enormous growth in doomsday logorrhoea. Frankly put, we face a bubble about bubbles.

It is a price index determined by measuring the price of a standard group of goods meant to represent the typical market basket of a typical urban consumer. Related, but different, terms are the CPI, the RPI, and the RPIX used in the United Kingdom. It is one of several price indices calculated by most national statistical agencies.

Am I beating the Dow? | Ask MetaFilter
How would I get a good approximation of a portfolio return on an investment account which has regular incoming and outgoing cash-flows, so that I can compare it to mutual fund and stock index performance? I have a trading account which I've deposited money in on an intermittent basis, to buy stocks, income trusts and mutual funds, and have on occasion withdrawn money when needed. Is there a simple and effective way to estimate the return in any particular stretch of time, or do we have to get into fairly complex mathematics? For instance, if I put in 40,000 and my portfolio goes up to 80,000, and then I take out 30,000, I ...
