Create a synthetic H2O Frame with random data. You can specify the number of rows/columns, as well as column types: integer, real, boolean, time, string, categorical. The frame may also have a dedicated "response" column, and some of the entries in the dataset may be created as missing.

Parameters:

dest - destination key

rows - Number of rows

cols - Number of data columns (in addition to the first response column)

seed - Random number seed that determines the random values

seed_for_column_types - Random number seed for setting the column types

randomize - Whether frame should be randomized

value - Constant value (for randomize=false)

real_range - Range for real variables (-range ... range)

categorical_fraction - Fraction of categorical columns (for randomize=true)

factors - Factor levels for categorical variables

integer_fraction - Fraction of integer columns (for randomize=true)

integer_range - Range for integer variables (-range ... range)

binary_fraction - Fraction of binary columns (for randomize=true)

binary_ones_fraction - Fraction of 1's in binary columns

time_fraction - Fraction of date/time columns (for randomize=true)

string_fraction - Fraction of string columns (for randomize=true)

missing_fraction - Fraction of missing values

has_response - Whether an additional response column should be generated

response_factors - Number of factor levels of the first column (1=real, 2=binomial, N=multinomial or ordinal)

positive_response - For real-valued response variable: Whether the response should be positive only.

_exclude_fields - Comma-separated list of JSON field paths to exclude from the result, used like: "/3/Frames?_exclude_fields=frames/frame_id/URL,__meta"
