Description
This function returns a positive number following exponential distribution. Using the inverse transform method, it can be proven that if variable x in the interval of (0,1) follows uniform distribution , -1/λ *lnx follows exponential distribution with parameter λ. So it simply uses cugen to generate a number between 0 and 1, and returns 1/ λ * logarithm of that number.
Usage
1
expgen(x)
Arguments
'λ' (the exponential distribution's parameter) is the function's argument,
Value
Returns a positive number following exponential distribution
Examples
1
2
3
a <- expgen(250)
