Determining the values of beta in a logistic regression equation

I read about logistic regression on Wikipedia and it talks of t开发者_运维百科he equation where z, the output depends on the values of beta1, beta2, beta3, and so on which are termed as regression coefficients along with beta0, which is the intercept.

How do you determine the values of these coefficients and intercept given a sample set where we know the output probability and the values of the input dependent factors?

Use R. Here's a video: www.youtube.com/watch?v=Yv05RjKpEKY
