The Weighted Linear Regression Is an extension of the standard Linear Regression, where a weight is added to each of the points.
It can be used to calculate the linear regression of the closing prices by considering the volume traded on each day, This indicator compared to the standard Linear Regression can indicate in which direction is moving the trading volume.
The function can also be used as a standard Linear Regression by specifying a "1" to the weight parameter.
Example:
temp1 = LinearReg_Wt(close, volume, 14);
This calculates the Weighted Linear Regression using the closing price of the last 14 days, considering the traded volume on each day.
