Just checking. Is there a study to perform a linear regression between subgraphs? or should I do it with a spreadsheet [or code one]? thanks, |

How would the calculation be done?

I want a number that quantifies for me how much subgraph A changes for a change in subgraph B, over N bars [N bars is time or volume] or: For a change in subgraph A over N bars, what is the change in subgraph B over N bars so: What's the linear relationship between X and Y N is an input A1 to AN the values of subgraph A over N bars B1 to BN the values of subgraph B over N bars I want as the output of the study the gradient M [+1 to -1] of a best fit straight line graph [A1 to AN] against [B1 to BN] Calculate the equation of the straight line y = -mx + C using least squares approach [?] [below from http://hotmath.com/hotmath_help/topics/line-of-best-fit.html] Step 1: Calculate the mean of the x-values and the mean of the y-values. Step 2: Compute the sum of the squares of the x-values. Step 3: Compute the sum of each x-value multiplied by its corresponding y-value. Step 4: Calculate the slope of the line ... [I can't copy/paste in the formulae from http://hotmath.com/hotmath_help/topics/line-of-best-fit.html] That slope is M it's my output +1 to -1 Date Time Of Last Edit: 2014-06-08 10:08:32

Just add the Study Subgraph Difference study to your chart and select the two lines as input then add a Moving Linear Regression Study and set Based On to the Study Subgraph Difference study.

Try the suggestion given in the prior post. Otherwise, for something like this, you really need to custom program it using ACSIL: http://www.sierrachart.com/index.php?l=doc/doc_CreatingDLLs.html Sierra Chart Support - Engineering Level Your definitive source for support.

Thanks vegasfoster. I've done just that. Tried it with the Subgraphs Ratio Study first which I thought would be it... but wasn't, not sure why? But yes what you suggest is helpful . Oh for the record I said M was +1 to -1 ..it's not is it....it can be any number. |
