Dear J folks,
I have a problem: I have monthly average temperatures and I need
interpolate daily values and I like to have a beautiful cyclic curve
fitting and resulting almiost the same monthly averages. It is
allowed to assume that all months are 30 days.
The monthly averages are in Centrigrades: tave=:_7.3 _6.6 _1.8 3.6
11.1 17.1 19.8 11.3 4.7 _1.3 _5.0
Yes, we are freezing 5 months a year. All help is appreciated. J
idioms are bonus.
Anssi
PS If somebody has deeper understanding over this problem and
temperature variation and knows good references I would like to
continue conversation privately.
