Postby maxchen » Thu Oct 03, 2013 4:37 am

EV8 32bit, 2013-10-01 patch

linear interpolation, ipolate produce different results compare to ADJUST's

Code: Select all

%pt = "Z:\2013\DL\EV8\Stats\"
%wf = %pt + "Data.wf1"
wfopen %wf

pageselect TimeSeries
smpl @all
series_NA.ipolate series_i    'at 1960M8, it is na
copy series_NA series_0
series_0.adjust ^   


compare series series_i and series_0, after 1960M7, ipolate ignore all the obs.

however, in http://www.eviews.com/Learning/statistics.html, p48 in pptx, the screenshot is from ADJUST, not from ipolate.
