Parameters
- seriesName
- The name of the series which will be displayed on the chart, i.e. its label.
- s
- A statistical series.
- lengthOfMA
- The number of periods over which the moving average is evaluated for each period.
Return Value
A series where the first term is the LWMA of lengthlengthOfMA for the
            latest period, the second term is the LWMA of length lengthOfMA for the previous 
            period and so on.

            is less than thelengthofMA. | 
 The Linearly Weighted Moving Average (LWMA) weights the time series by assigning a weight of 1, 
            to the oldest price and a weight of 2, to the second oldest price and so on... Until the weight of the most 
            recent value is assigned to be the parameter 
            
            
            lengthOfMA, after which the LWMA is given by the sum 
            of the weighted prices divided by the sum of the weights. This indicator then shifts the window 
            (one place back) over which the MA is evaluated and the indicator is then re-evaluated.
