Detailed Description

Represents a matrix of statistical collectors for functions of multiple means.

Each element of such a matrix is an instance of

umontreal.ssj.stat.FunctionOfMultipleMeansTally, and observations can be added with the add(double[][][]) method. This class defines a factory method to construct a matrix of tallies computing the same function and sharing the same dimension.

Constructor & Destructor Documentation

◆ MatrixOfFunctionOfMultipleMeansTallies() [1/2]

umontreal.ssj.stat.matrix.MatrixOfFunctionOfMultipleMeansTallies< E extends FunctionOfMultipleMeansTally >.MatrixOfFunctionOfMultipleMeansTallies ( int numRows,
int numColumns )

Constructs a new unnamed matrix of function of multiple means tallies with numRows rows, and numColumns columns, and filled with null references.

Parameters
numRowsthe number of rows in the matrix.
numColumnsthe number of columns in the matrix.
Exceptions
NegativeArraySizeExceptionif `numRows` or `numColumns` are negative.

◆ MatrixOfFunctionOfMultipleMeansTallies() [2/2]

umontreal.ssj.stat.matrix.MatrixOfFunctionOfMultipleMeansTallies< E extends FunctionOfMultipleMeansTally >.MatrixOfFunctionOfMultipleMeansTallies ( String name,
int numRows,
int numColumns )

Constructs a new empty matrix of function of multiple means tallies with name name, numRows rows, and numColumns columns, and filled with null references.

Parameters
namethe global name of the matrix.
numRowsthe number of rows in the matrix.
numColumnsthe number of columns in the matrix.
Exceptions
NegativeArraySizeExceptionif `numRows` or `numColumns` are negative.

Member Function Documentation

◆ add() [1/2]

For each function of multiple means tally with row index r and column index c, adds the vector of observations x[r][c] if collecting is turned ON.

Parameters
xthe vectors of observations to be added.
Exceptions
IllegalArgumentExceptionif the dimensions of `x`, `x[r]`, or x[r][c] are incorrect.

Definition at line 110 of file MatrixOfFunctionOfMultipleMeansTallies.java.

◆ add() [2/2]

Equivalent to add(x.toArray()), without copying the elements of x into a temporary 3D array.

Each slice of the 3D matrix x corresponds to a row of the matrix of probes. Each row of the 3D matrix corresponds to a column of the matrix of probes. Each column of the 3D matrix corresponds to a component of a vector of observations added to a function of multiple means tally. This can be used only when all the function of multiple means tallies in the array share the same dimension.

Parameters
xthe matrix of observations.
Exceptions
IllegalArgumentExceptionif the dimensions of the matrix are incorrect.

Definition at line 137 of file MatrixOfFunctionOfMultipleMeansTallies.java.

◆ addSameDimension()

For each element (r, c) of this matrix of tallies, adds the vector of observations x[0].get (r, c), …, x[d-1].get (r, c).

This method can be used only when all tallies in this matrix share the same dimension. It creates a transposed 3D array compatible with add(double[][][]), and calls the latter method with this array. For example, let mt be a matrix of tallies with dimensions

\(r\times c\) whose l  \(=rc\) elements correspond to ratios. If a program can generate two matrices num and den of dimensions \(r\times c\) representing observations for the numerator and denominator of the ratios, respectively, the observations can be added using mt.add (num, den) instead of creating an intermediate 3D array of observations.

Parameters
xthe array of matrices of observations.
Exceptions
IllegalArgumentExceptionif the length of `x` does not correspond to the dimension of the tally, or the dimensions of the matrices x[j] are not equal for all j=0,…,d-1.

Definition at line 170 of file MatrixOfFunctionOfMultipleMeansTallies.java.

◆ areAllNumberObsEqual()

Tests that every tally in this matrix contains the same number of observations.

This returns true if and only if the matrix has no row and no column, or if all tallies have the same number of observations.

Returns
the success indicator of the test.

Definition at line 233 of file MatrixOfFunctionOfMultipleMeansTallies.java.

◆ average()

Computes the average for each function of multiple means tally in the matrix.

If the tally \((r, c)\) has no observation, the Double.NaN value is stored in the given matrix, at row r, column c.

Definition at line 251 of file MatrixOfFunctionOfMultipleMeansTallies.java.

◆ clone()

Clones this object.

Makes a shallow copy of this matrix, i.e., does not clone all the probes in the matrix.

Definition at line 316 of file MatrixOfFunctionOfMultipleMeansTallies.java.

◆ create()

This factory method constructs and returns a matrix of function of multiple means tallies with numRows rows, numColumns columns, and filled with instances of
.

umontreal.ssj.stat.FunctionOfMultipleMeansTally. Each tally computes the multivariate function func, in d dimensions.

Parameters
functhe multivariate function computed by the tallies.
dthe dimension of the tallies.
numRowsthe number of rows in the matrix.
numColumnsthe number of columns in the matrix.
Returns
the created matrix.

Definition at line 91 of file MatrixOfFunctionOfMultipleMeansTallies.java.

◆ getDimension()

Assuming that each tally in this matrix has the same dimension, returns the dimension of tally (0, 0), or 0 if the matrix has no row or column.

Returns
the dimension.

Definition at line 205 of file MatrixOfFunctionOfMultipleMeansTallies.java.

◆ numberObs()

Assuming that each tally in this matrix contains the same number of observations, returns the number of observations in tally (0, 0), or 0 if the matrix has no row or column.

Returns
the number of observations.

Definition at line 219 of file MatrixOfFunctionOfMultipleMeansTallies.java.

◆ standardDeviation()

For each tally in the matrix, computes the standard deviation, and stores it into the matrix m.

This is equivalent to calling variance(DoubleMatrix2D) and performing a square root on every element of the filled matrix.

Parameters
mthe matrix to be filled with standard deviations.
Exceptions
NullPointerExceptionif `m` is `null`.
IllegalArgumentExceptionif `m.rows()` does not correspond to umontreal.ssj.stat.matrix.MatrixOfStatProbes.rows, or m.columns() does not correspond to umontreal.ssj.stat.matrix.MatrixOfStatProbes.columns.

Definition at line 298 of file MatrixOfFunctionOfMultipleMeansTallies.java.

◆ variance()

For each tally in the matrix, computes the sample variance, and stores it into the given matrix.

If, for some tally \((r, c)\), there are not enough observations for estimating the variance, Double.NaN is stored in the corresponding element of the given matrix m.

Parameters
mthe matrix to be filled with sample variances.
Exceptions
NullPointerExceptionif `m` is `null`.
IllegalArgumentExceptionif `m.rows()` does not correspond to umontreal.ssj.stat.matrix.MatrixOfStatProbes.rows, or m.columns() does not correspond to umontreal.ssj.stat.matrix.MatrixOfStatProbes.columns.
