search for: segment3

...to divide the series into segments and then to apply linear regression models on each segment but in a "global way" and considering heteroskedasticity between the segments. For example, I build a time series y with 3 segments: segment1=1:20+rnorm(20,0,2) segment2=20-2*1:30+rnorm(30,0,5) segment3=-40+0.5*1:15+rnorm(15,0,1) group=c(rep(1,20),rep(2,30),rep(3,15)) y=c(segment1,segment2,segment3) Data=data.frame(y,t=1:65,group=as.factor(group)) the model I'd like to fit is: y_t= (beta_01+beta_11*t+error_1)*(group==1)+(beta_02+beta_12*t+error_2)*(group==2)+(beta_03+beta_13*t+error_3)*(gr...

...the documentation I would create a text file named document_database.txt that might have the following: remote 192.168.1.10:30000 chert /var/lib/xapian_database/segment1 remote 192.168.1.10:30000 chert /var/lib/xapian_database/segment2 remote 192.168.1.10:30000 chert /var/lib/xapian_database/segment3 etc. I would then in my PHP program open document_database.txt as the database and then perform normal Xapian calls. The same with Omega, I would, in my template, change the database name to document_database.txt. Given the above, it appears that I do not have to refer to each segment (segme...

...t all segments with the same attributes. i.e. it seems to be ignoring the "groups" #The answer I want: Segment1 has co-ordinates (0,0, x2=-0.25, y2 = -0.5) and be solid, red and of width 1.25 Segment2 has co-ordinates (0,0, x2=0.25, y2 = 0) and be dashed, black and of width 0.75 Segment3 has co-ordinates (0,0, x2=0.8, y2 = 0.75) and be dotted, blue and of width 1.25 Any help is much appreciated.
