I have some data (inputClosePrice)
i log it, detrend it, and then normalise it.
How can i now get back to the intial set of data for a given point?
I've had a look at the retrend function,however, in the example they talk abotu iddata, linear ARX model, simulate model, and i do none of that, as part of my detrending process, so i'm unsure what to send the retrend function.
--- sample of my code given below:
sdata_log = log10(inputClosePrice);
detrend_LogPrice = detrend(sdata_log, inputPolyDegree);
normalised_detrendedData = detrend_LogPrice;
