If your dichotomous dependent variable is Y, coded with two
different values and you have an independent variable X, you need to
create a variable N to denote the number of trials. And we can set N=1 for all
observations in this case.
Now when you are prompted to enter variables in Probit Analysis dialogue
box, you enter:
Y as response category
N as total observed
X as covariates.
If you are using syntax, this can be done as follows:
compute n = 1.
probit y of n with x
