Question related to combination and the corresponding probability
Dear r users,
I have 4 variables x1,x2,x3,x4 and each one has two levels, for example Y
and N.
For x1: prob(Y)=0.6, prob(N)=0.4;
For x2: prob(Y)=0.5, prob(N)=0.5;
For x3: prob(Y)=0.8, prob(N)=0.2;
For x4: prob(Y)=0.9, prob(N)=0.1;
Therefore, the sample space for (x1, x2, x3, x4)={YYYY, YYYN, YYNY,......}
(16 possible combination) and the corresponding probabilities are
{(0.6)(0.5)(0.8)(0.9),

merge two dataset and replace missing by 0
Hi r users,
I have two data sets (X1, X2). For example,
time1<-c( 0, 8, 15, 22, 43, 64, 85, 106, 127, 148, 169, 190 ,211 )
outpue1<-c(171 ,164 ,150 ,141 ,109 , 73 , 47 ,26 ,15 ,12 ,6 ,2 ,1 )
X1<-cbind(time1,outpue1)
time2<-c( 0 ,8 ,15 , 22 ,43 , 64 ,85 ,106 ,148)
output2<-c( 5 ,5 ,4 ,5 ,5 ,4 ,1 ,2 , 1 )
X2<-cbind(time2,output2)
