dear fellows !
I have a snappy curve(y(x)) which looks like the sum of two Gau�-functions a
great and a little
hump.I use > integ y x,gen(Sy) and line y Sy x < to get the
integral-function above.
the result-curve .line Sy x seems to be the "sum" of two nearly straight
lines with different
k- values(y = k*x+d) that means from 0 to 5 I have k1 and from 5 to 10 I
have k2.
Now I'd like to make linear regression for both
parts(region1<->k1,region2<->k2)
in one commandline.Is this possible ?
thank you very much andreas
