Hello All,
Tech support tells me that there's no way to do curvilinear
regression analysis in Metastock formula language. They suggest
getting a MetDevKit and create an external DLL and import the
results to Metastock. However, I don't know any programming
language, and wonder if anyone knows of a resource somewhere that I
could access.
What I'm interested in is the quadratic least squares curve, of the
form Y=a+bX+cXsquared, with inputs for data array and lookback
periods and which could be plotted as an indicator. I'd also like
to be able to plot and system test these associated formulas:
Curvilinear Slope (b+c); Curvilinear rsquared; and Curvilinear
Standard Error.
Although the definition formulas for the latter two are the same as
for the built-in Linear Regression, the computation formulas are not
as they are derived from the quadratic (parabolic) regression.
My reason for wanting this has probably occurred also to others: the
moving Linear Regression tracks prices very well, better than any
moving average, but lags at inflection points (changes in
direction.) The moving parabolic least squares is very likely to
respond much faster.
Since it's likely that someone has already had this idea and these
formulas exist somewhere in a form I could import to MetaStock, I'd
certainly appreciate knowing about it. Any other thoughts on this
would also be welcome.
Thanks,
Dick
