inspect_par_beta
checks if an object is an eligible vector of
parameters for the Beta distribution. This can be useful to validate inputs,
intermediate calculations or outputs in user-defined functions.
1 |
x |
An arbitrary object. |
inspect_par_beta
conducts a series of tests to check if x
is an
eligible vector of parameters for the Beta distribution. Namely,
inspect_par_beta
checks if:
x
is NULL
or empty.
x
is an atomic vector
x
is numeric
x
has length
2
x
has NA
or NaN
values.
All elements of x
are positive.
inspect_par_beta
does not return any output. There are two possible
outcomes:
The call is silent if x
is an eligible vector of parameters for the Beta
distribution.
An informative error message is thrown otherwise.
inspect_par_bernoulli
to validate parameters for
the Bernoulli/Binomial distribution.
inspect_par_multinomial
to validate parameters for
the Multinomial distribution.
inspect_par_dirichlet
to validate parameters for
the Dirichlet distribution.
inspect_par_haldane
to validate parameters for the
Haldane distribution.
