The defintion of the sequency of probability was wrong!
> p_11=seq(0,1,0.1)
> p_12=seq(0,1,0.1)
Since your multinomial distribution requires P_11, P_12, P13=1-P_11-P12 be
greater than or equal to zero and P_11+P_12+P_13 = 1. In your above
definition of P_11[6] =P_12[6]= 0.6, P_11[7] = P_12[7] = 0.7, ..., P_11[10]
=P_12[10]=1.0. For these pairs 1-p_11-p_12 < 0! There is why you had the
error message!
> X_1=rmultinom(n-q+1,size=1,prob=cbind(p_11,p_12,(1-p_11-p_12)))
Suggested Solution:
Redefine P_11 and P_12 such that P_11[i] + P_12[i] <1 for all i! This will
sove your problem!
# you choose whatever a and b such that a+b<=1. for example,
a = 0.4
b = 0.6
# you need to adjust the increaments to get vectors with equal length.
p_11=seq(0,a,0.05*a)
p_12=seq(0, b,0.05*b)
