Hi everyone. My problem: I've 4 distributions: A, B, C and D: #A mA=16.6 sA=3.0 #B mB=18.9 sB=3.2 #C mC=20.3 sC=2.1 #D mD=24 sD=0.8 ###Graphiques ensembles plot(function(x) dnorm(x,mA,sA),0,40,col="orange",ylim=c(0,0.5)) plot(function(x) dnorm(x,mB,sB),0,40,add=T,col="green") plot(function(x) dnorm(x,mC,sC),0,40,add=T,col="blue") plot(function(x) dnorm(x,mD,sD),0,40,add=T,col="red") Now I've a fifth distribution X #X mX=23 sX=0.7 plot(function(x) dnorm(x,mX,sX),0,40,add=T,col="black") And I would like to know the area of the overlapping of the curve of X with the curves of A, B, C and D (in %). How can I do that?
Integrate over the differences? Uwe Ligges
