Stats

random variable (RV)

is a function
i.e. number of coin tosses till H

w: H,TH,TTH, ...
x = 0,1,2...


X: w --> x: H --> 1, TH --> 2



Stats

probability mass function (PMF)

probability of having getting a heads on 1, 2, . . . tosses

(every discrete random variable X has it associated with it)

Stats

probability distribution functions (PDFs)

Continuous RVs has it

Stats

cumulative distribution function

cumulative probability of getting a heads in 1 or less tosses; 2 or less tosses

(discrete case)

Stats

binomial random variable

probability of x successes out of n is defined by the pmf

toss a coin n = 10 times
success and failure, each with probability θ and (1 − θ)

Stats

What’s the probability of x or fewer successes, where x is some number between 0 and 10?

CDF function pbinom

Stats

What is the probability of getting exactly x successes?

answer from (a) the cdf, or (b) the pmf

Stats

define the discrete binomial random variable X

  • function X : S → R, where S is the set of outcomes (i.e.,
    outcomes are ω ∈ S)
  • X(ω) = x, and SX is the support of X (i.e., x ∈ SX)
  • A PMF is defined for X
  • A CDF is defined for X

Stats

associated R function


  • pdf
  • cdf
  • dnorm
  • pnorm

Stats

The area under curve between +infty and -infty

pnorm(Inf)-pnorm(-Inf)

Stats

The area under curve between 2 and -2

pnorm(2)-pnorm(-2)

Stats

The area under curve between 1 and -1

pnorm(1)-pnorm(-1)
