Hi., Lets take two case,
Case_1: p = 0.9 then odd_1 = 0.9/0.1 =9
Case_2: p = 0.5 then odd_2 = 0.5/0.5 = 1
now odd ratio = 9/1 = 1 which violates the range [0,1].
Am I missing something ?
Covariance is the concept of variance to multiple random variables. Instead of measuring the fluctuation of a single random variable, the covariance measures the fluctuation of two variables with each other.
- Var[X+Y] = Var[X] + Var[Y] + 2.XY.Cov(X,Y) ?
A Random variable is a variable whose value is determined by some random event. The Expectation of random variable ‘X’ i.e. E[X] is the central tendency of X when picked once randomly from the sample space (i.e. a homogeneous/ heterogeneous space of all possible outcome).
- E[X+c] = ?
