General statistical functions.
log-row-stochastic-map?
(log-row-stochastic-map? m & {:keys [decimal], :or {decimal 10}})Returns true if the map is logarithmically stochastic to the given precision.
log-stochastic-map?
(log-stochastic-map? m & {:keys [decimal], :or {decimal 10}})Returns true if the map is logarithmically stochastic to the given precision.
random-row-stochastic-map
(random-row-stochastic-map row-keys col-keys)Returns a nested hash-map representing a row-stochastic matrix. The outer key corresponds to a row, and the nested key corresponds to a column.
For example, take the matrix X given by:
0 1 2
+-------+
0 | a b c |
1 | d e f |
2 | g h i |
+-------+
To obtain the element d, one could use (get-in X [1 0]), or to obtain the element h, one could use (get-in X [2 1]).
random-stochastic-map
(random-stochastic-map keys)Returns a hash-map representing a randomly distributed stochastic vector.
random-stochastic-vector
(random-stochastic-vector size)Returns a randomly generated stochastic vector of the given size.
row-stochastic-map?
(row-stochastic-map? m & {:keys [decimal], :or {decimal 10}})Returns true if the map is row stochastic to the given precision.
stochastic-map?
(stochastic-map? m & {:keys [decimal], :or {decimal 10}})Returns true if the map is stochastic to the given precision.
uniform-row-stochastic-map
(uniform-row-stochastic-map row-keys col-keys)Returns a nested hash-map representing a row-stochastic matrix. The outer key corresponds to a row, and the nested key corresponds to a column.
For example, take the matrix X given by:
0 1 2
+-------+
0 | a b c |
1 | d e f |
2 | g h i |
+-------+
To obtain the element d, one could use (get-in X [1 0]), or to obtain the element h, one could use (get-in X [2 1]).
uniform-stochastic-map
(uniform-stochastic-map keys)Returns a hash-map representing a uniformly distributed stochastic vector.
uniform-stochastic-vector
(uniform-stochastic-vector size)Returns a uniformly distributed stochastic vector of the given size.
