Please help me with writing this code, it's R. Summarizing data 11 Now that you've seen the function sapply() , you'll practice writing your own functions to apply! The first step is defining a function that ouputs summary statistics. Packaging common operations into functions allows you to avoid repeating yourself. To define your own function in R, you'll use the syntax function_name <- function(args, more_args) { } where the is replaced with whatever operations using args and more_args you want...
12. Let M be the set of continuous functions on R which vanish outside a finite interval (the interval may depend on the function). (a) Show that M is a metric space in the sup norm. (b) Show that M is not complete. Chapter 5. Sequences of Function 210 (C) Show that C.(R), the continuous functions which go to zero et is complete in the sup norm (problem 10 of Section 5.3). (d) Prove that Mis dense in Co(R). T...

7. Consider a family of maps f :R-R, where f(r)= 2+c, cE R. a) Let c 0. Find all the fixed points of f and analyze the map by drawing a cobweb. Check stability of the fixed points b) Find and classify all the fixed points of f as a function of c. c) Find the values of c at which the fixed points bifurcate, and classify those bifurcations. d) For which values of c is there an attracting cycle...
In this problem we consider only functions defined on the real numbers R. A function f is close to a function g if 3x E R s.t. Vy E R, A function f visits a function g when Vz E R, R s.t. a<y and f() -g) For a given function f and n E N, let us denote by n the following function: n(x)-f(x)+2" Below are three claims. Which ones are true and which ones are false? If a...

For each of the following functions, determine the value of c for which the function is a joint pdf of two continuous random variables X and Y. (a) f(x,y) = cry, 0 <r<1,7 <y<r. (b) f(r,y) = c(1+r+y), 0 <r<y<1. (c) f( y) = cye.0<r<y.0<y<1. (d) f(x,y) = csin(x+y), 0<I< /2.0 <y < /2. (e) f(x,y) = cr(1-y), 0 <y<1,0 <r<1-y.
