I have run a probit regression on a sample of 50 companies using the XLSTAT package on Excel.
I am having trouble understanding the output. is it that the sample is too small for this kind of analysis. the population is N = 60
I am attaching the output screenshot.
In statistics, a probit model is a type of regression where the dependent variable can take only two values.
The information on this link will be very helpful

If this is serious work I would not use ExCel. It has problems see: https://www.google.com/search?q=reasons+to+not+use+excel+in+statistics&oq=reasons+to+not+use+excel+in+statistics&aqs=chrome..69i57.20842j1j4&sourceid=chrome&ie=UTF-8
Now on probit models see: https://www.google.com/search?q=Probit+models+R+examples&oq=Probit+models+R+examples&aqs=chrome..69i57j0l2.16059j0j8&sourceid=chrome&ie=UTF-8
These and this might get you started , See my post:

Investigador anonimo: Solamente cuando la población tiene tamaño mayor de 100 se justifica realizar muestreo. Por tanto, en su caso N =n= 60 .
Con este tamaño de datos, ya puede realizar su regresion.
Cordialmente.
