Logistic regression

#1
Hello everybody,
I hope someone can help me.
I do not understand how to calculate log odds. I know how to calculate odds and proportions and I understand what differ between them. I just do not know how we get the log odds.
Log odds are supposed to help us since it can treat any value between - ∞ and + ∞ . Moreover, they can be useful when proportions are not symmetric. But I just do not know how to get them.
I just do not understand the formula:

You wrote the correct formula, if you find the β0 and β1, using the logistic regression you can calculate the log odds.
The linear regression finds the coefficients that maximize the log of the likelihood (log-likelihood ) that you will get your sample results
