anyvalue(), anymatch(), and anycount() are for categorical or other variables taking integer
values. If we define a subset of values specified by an integer numlist (see [U] 11.1.8 numlist),
anyvalue() extracts the subset, leaving every other value missing; anymatch() defines an indicator
variable (1 if in subset, 0 otherwise); and anycount() counts occurrences of the subset across a set
of variables. Therefore, with one variable, anymatch(varname) and anycount(varname) are
equivalent.
With the auto dataset, we can generate a variable containing the high values of rep78 and a
variable indicating whether rep78 has a high value:

In Bayesian analysis, we can use previous information, either belief or experimental evidence, in
a data model to acquire more balanced results for a particular problem. For example, incorporating
prior information can mitigate the effect of a small sample size. Importantly, the use of the prior
evidence is achieved in a theoretically sound and principled way.
By using the knowledge of the entire posterior distribution of model parameters, Bayesian inference
is far more comprehensive and flexible than the traditional inference.
Bayesian inference is exact, in the sense that estimation and prediction are based on the posterior
distribution. The latter is either known analytically or can be estimated numerically with an arbitrary
precision. In contrast, many frequentist estimation procedures such as maximum likelihood rely on
the assumption of asymptotic normality for inference.

How to do Bayesian analysis
Bayesian analysis starts with the specification of a posterior model. The posterior model describes
the probability distribution of all model parameters conditional on the observed data and some prior
knowledge. The posterior distribution has two components: a likelihood, which includes information
about model parameters based on the observed data, and a prior, which includes prior information
(before observing the data) about model parameters. The likelihood and prior models are combined
using the Bayes rule to produce the posterior distribution
