Hello, 

 

Lets assume I have an ordinal response variable representing the
D<-c(D0,D1,D2,D3,D4) where D0 is no damage and D4 is collapse which I want
to correlate with a continuous predictor variable, wind speed at the
location of each building.

 

is  there a function in R which I can use to estimate the sample size of
buildings with a given power if I want to perform an ordinal logistic
regression? Is this sample the same if I want to use kernel smoothing? Is
this possible to estimate the sample size in D0,.,D4? Collapse is rather
rare.    

 

Regards, 

Yanna
