Is it useful to set a fraction number here to the mask value?

[Robert]

Hi,

I am new to Python. Now I follow a thread on mask array usage on line:


https://stackoverflow.com/questions/31563970/fitting-a-binomial-distribution-with-pymc-raises-zeroprobability-error-for-certa


I understand the problem, but I don't understand the answer follow the link.

Because the 'mask' array is composed of integer, if it is assigned a fraction
number as suggested a 1.5, it will be formatted to an integer 1.
 

observed_values = sp.random.binomial(n = 10.0, p = 0.1, size = 100)
...
mask = sp.zeros_like(observed_values)


Are you clear the answer's meaning?


"You can give it a non-integer value in order to avoid the problem that you cite. 
For example, if you fill with, say, 1.5 that should work."




Thanks in advance
