Hello everyone. I am quite new to R and I would appreciate some help in figuring out what I am doing wrong.
For the following code:
> #with cost
>
> m.control=c(1.45,9.40,9.96,4.2,1.86,0.2)
> m.sham=c(3.39,23.94,23.62,10.08,2.99,1.09)
>
> t.control=function(m, a){(1-exp(-a*m)*(1-(1/30)*m))}
> t.sham=function(m, a, d){(1-exp(-a*(1-d)*m)*(1-(1/30)*m))}
>
> t.sham(2, 2, 0.1)
[1] 0.9744979
> t.control(2, 2)
[1] 0.9829054
>
> #without cost
>
> m.control=c(1.45,9.40,9.96,4.2,1.86,0.2)
> m.sham=c(3.39,23.94,23.62,10.08,2.99,1.09)
>
> t.control=function(m, a){(1-exp(-a*m))}
> t.sham=function(m, a, d){(1-exp(-a*(1-d)*m))}
>
> t.sham(2, 2, 0.1)
[1] 0.9726763
> t.control(2, 2)
[1] 0.9816844
As you can see the values I am getting for t.control and t.sham are larger in the "with cost" scenario and this shouldn't be the case. (the cost is 1-1/30*m). Is there something wrong I did when defining t.sham and t.control in the "with cost" section that I am failing to see?
