Welcome to the Wealth-Lab 5 Wiki:


The same link is available when clicking "More info..." in the Indicator list. The indicator is applied to DataSeries, not to an array, because WL operates with series.

see this post (about 2/3 down)

i wish to create it on a price array is it possible?

you can create regressions on just about any dataseries. many quant types will say that the results you get will be useless in making predictions when you calculate regressions based on price data however. i think they would suggest not using price data, but instead the log return series. my own view is that using a regression on a price series is probably better (at least no worse) than using a moving average of price to make trading decisions.

Eugene, i just saw your response. Does the Wealth-Lab LinearReg function return Alpha? I didn't think it did.

Steve, I was merely replying to the quoted text re: how to "create a linear regression" in WL.
