i'm sorry i'll try to be more precise and to be better understood
i'm goin to write down all the steps i took so far:
i first studied the stationarity of two time series: google search and bitcoin price. (by "google search" i mean the number of times the word BITCOIN is typed in a day, using google as search engine; then i considered the daily google searches, so that i could find how many times BITCOIN was typed every single day).
i downloaded a plug-in system to be able to use the ADFTest function in excel and i found that both time series are non- stationary on the basis of the ADF test.
now that i know they're both non-stationary, (this means they both have an integration of order 1, aka I(1)) i wish i could study the cointegration between the two series, but to do so, i need to know the residuals of the functions y=alfa+Beta*x+e (where "e" is the residual i need, and "y" the function used for the cointegration)
can anyone tell me where to find those residuals???
thank u so much!!!!
