- All 1010data Functions
  1010data provides a whole range of functions that can provide information and act on your data.
- Time/Date functions
  The time/date functions are vector functions that operate on columns containing time-related data and return specific information about the date/time for each row.
- Group functions (g_functions)
  Group functions, or g_functions, are used to perform operations, such as summarizations, on rows that have the same values in a set of given columns.
  - Using g_functions
    Provides an overview of basic functionality of g_functions in 1010data.
  - Creating a selection column
    All g_functions contain an optional S parameter, or a selection column, to tell the g_function whether to include or exclude a row in its calculations.

  - Miscellaneous
- Math functions
  Math functions are vector functions that perform mathematical operations on one or more columns and return a column of results based on the operation.
- Matrix functions
- Categorization functions
  Categorization functions are vector functions that organize data and determine logical groupings. These functions can be used for conditionalizing results and/or bucketing value ranges.
- String functions
  String functions are vector functions that manipulate vectors of strings to provide information about a string or substring, concatenate and split strings, or transform strings based on specified criteria.
- List functions
  List functions are scalar functions that return lists, subsets of lists, and combinations of lists, among other functionality. Lists, along with packages, are compound scalar data types that facilitate programmatic interaction with scalar data values and variables.
- Data-handling functions
  Data-handling functions are vector functions that return a hash value based on an input column or columns.
- Row functions
  Row functions are vector functions that return computational outputs for row inputs, as opposed to column outputs. Row inputs are defined as a space- or comma-separated list of column names.

  The object functions can be used to check the existence, type, and accessibility of objects such as folders, tables, and queries on the 1010data Insights Platform.
- Miscellaneous functions
  This category of functions contains special functions that don't neatly fit into other categories of functions.

`param(M;P;I)`

Returns the numerical value of a particular model parameter extracted from a discrete or continuous model.

Syntax

param(M;P;I)

Input

Argument Type Description

M

model

The name of a column that contains a model as returned by a discrete or continuous modeling function

These functions include:

g_lsq(G;S;Y;XX)
g_wlsq(G;S;Y;W;XX)
g_logreg(G;S;Y;XX;Z)
g_pca(G;S;XX;Z)
g_cluster(G;S;XX;A;N;Z)
g_liblinear(G;S;Y;XX;Z)
g_glm(G;S;Y;XX;Z)

P

text

The name of the particular parameter to be extracted from the model

Note: See the descriptions of the individual modeling functions for more information on the values that can be specified for P.

I

integer

An index (or list of indices) specifying which value is to be returned

For single-value parameters, I should be left blank.

For multiple-value parameters, I should be a single integer specifying which value is to be returned.

For multidimensional parameters, I should contain as many integers as there are dimensions.

Return Value

Returns a decimal number corresponding to the value of the parameter named P extracted from the model M, possibly indexed by the value or values in I.
