Methods
distribution()
BETADIST.
public
static distribution(mixed $value, mixed $alpha, mixed $beta[, mixed $rMin = 0.0 ][, mixed $rMax = 1.0 ]) : array<string|int, mixed>|float|string
Returns the beta distribution.
Parameters
- $value : mixed
-
Float value at which you want to evaluate the distribution Or can be an array of values
- $alpha : mixed
-
Parameter to the distribution as a float Or can be an array of values
- $beta : mixed
-
Parameter to the distribution as a float Or can be an array of values
- $rMin : mixed = 0.0
-
as an float Or can be an array of values
- $rMax : mixed = 1.0
-
as an float Or can be an array of values
Return values
array<string|int, mixed>|float|string —If an array of numbers is passed as an argument, then the returned result will also be an array with the same dimensions
incompleteBeta()
Incomplete beta function.
public
static incompleteBeta(float $x, float $p, float $q) : float
Parameters
- $x : float
-
require 0<=x<=1
- $p : float
-
require p>0
- $q : float
-
require q>0
Tags
Return values
float —0 if x<0, p<=0, q<=0 or p+q>2.55E305 and 1 if x>1 to avoid errors and over/underflow
inverse()
BETAINV.
public
static inverse(mixed $probability, mixed $alpha, mixed $beta[, mixed $rMin = 0.0 ][, mixed $rMax = 1.0 ]) : array<string|int, mixed>|float|string
Returns the inverse of the Beta distribution.
Parameters
- $probability : mixed
-
Float probability at which you want to evaluate the distribution Or can be an array of values
- $alpha : mixed
-
Parameter to the distribution as a float Or can be an array of values
- $beta : mixed
-
Parameter to the distribution as a float Or can be an array of values
- $rMin : mixed = 0.0
-
Minimum value as a float Or can be an array of values
- $rMax : mixed = 1.0
-
Maximum value as a float Or can be an array of values
Return values
array<string|int, mixed>|float|string —If an array of numbers is passed as an argument, then the returned result will also be an array with the same dimensions
evaluateArrayArguments()
Handles array argument processing when the function accepts multiple arguments, and any of them can be an array argument.
protected
static evaluateArrayArguments(callable $method, mixed ...$arguments) : array<string|int, mixed>
Example use for: ROUND() or DATE().
Parameters
- $method : callable
- $arguments : mixed
Return values
array<string|int, mixed>evaluateArrayArgumentsIgnore()
Handles array argument processing when the function accepts multiple arguments, and any of them can be an array argument except for the one specified by ignore.
protected
static evaluateArrayArgumentsIgnore(callable $method, int $ignore, mixed ...$arguments) : array<string|int, mixed>
Example use for: HLOOKUP() and VLOOKUP(), where argument 1 is a matrix that needs to be treated as a database rather than as an array argument.
Parameters
- $method : callable
- $ignore : int
- $arguments : mixed
Return values
array<string|int, mixed>evaluateArrayArgumentsSubset()
Handles array argument processing when the function accepts multiple arguments, but only the first few (up to limit) can be an array arguments.
protected
static evaluateArrayArgumentsSubset(callable $method, int $limit, mixed ...$arguments) : array<string|int, mixed>
Example use for: NETWORKDAYS() or CONCATENATE(), where the last argument is a matrix (or a series of values) that need to be treated as a such rather than as an array arguments.
Parameters
- $method : callable
- $limit : int
- $arguments : mixed
Return values
array<string|int, mixed>evaluateArrayArgumentsSubsetFrom()
Handles array argument processing when the function accepts multiple arguments, but only the last few (from start) can be an array arguments.
protected
static evaluateArrayArgumentsSubsetFrom(callable $method, int $start, mixed ...$arguments) : array<string|int, mixed>
Example use for: Z.TEST() or INDEX(), where the first argument 1 is a matrix that needs to be treated as a dataset rather than as an array argument.
Parameters
- $method : callable
- $start : int
- $arguments : mixed
Return values
array<string|int, mixed>evaluateSingleArgumentArray()
Handles array argument processing when the function accepts a single argument that can be an array argument.
protected
static evaluateSingleArgumentArray(callable $method, array<string|int, mixed> $values) : array<string|int, mixed>
Example use for: DAYOFMONTH() or FACT().
Parameters
- $method : callable
- $values : array<string|int, mixed>
