Summary

English: This image is an example of a Tukey biweight function. It was created under R by the following code:

f = function(x, c) { 

   if (abs(x) < c) {
       return(x*((1-(x/c)^2))^2)
   }
   else {
       return(0)
   }

}

x= (-1000:1000)/100

y[1] = f(x[1], 3)

for (i in x[-1]) {y = c(y, f(i, 3))}
