Syntax Description
Returns the variance of all cells of a database field in all records
that match the specified search_criteria. The records from the
example are treated as a sample of data. A representative result
of a large population cannot be obtained from a sample population
of fewer than one thousand.
Calculates the variance of all cell values in a database field in all
records that match the specified search_criteria. The records are
from the example are treated as an entire population.
FREQUENCY(data; classes) Calculates the frequency distribution in a one-column-array. The
default value supply and the number of intervals or classes are
used to count how many values are omitted on the single
intervals. Data is the array of, or reference to, the set of values to
be counted. Classes is the array of the class set.
GROWTH(data_Y; data_X;
new_data_X; function_type)
LINEST(data_Y; data_X;
linear_type; stats)
LOGEST(data_Y; data_X;
function_type; stats)
Calculates the points of an exponential trend in an array. Data_Y
is the Y Data array. Data_X (optional) is the X Data array.
New_Data_X (optional) is the X data array, in which the values
are recalculated. Function_type is optional. If function_type = 0,
functions in the form y = m^x are calculated. Otherwise, y = b*m^x
functions are calculated.
Returns the parameters of a linear trend. Data_Y is the Y Data
array. Data_X (optional) is the X Data array. Linear_Type
(optional): If the line goes through the zero point, then set
Linear_Type = 0. Stats (optional): If Stats=0, only the regression
coefficient is calculated. Otherwise, other statistics will be seen.
Calculates the adjustment of the entered data as an exponential
regression curve (y=b*m^x). Data_Y is the Y Data array. Data_X
(optional) is the X Data array. Function_type (optional): If
function_type = 0, functions in the form y = m^x are calculated.
Otherwise, y = b*m^x functions are calculated. Stats (optional). If
Stats=0, only the regression coefficient is calculated.
MDETERM(array) Returns the array determinant of an array. This function returns a
value in the current cell; it is not necessary to define a range for
the results. Array is a square array in which the determinants are
defined.
MINVERSE(array) Returns the inverse array. Array is a square array that is to be
inverted.
MMULT(array; array) Calculates the array product of two arrays. The number of
columns for array 1 must match the number of rows for array 2.
The square array has an equal number of rows and columns.
Array at first place is the first array used in the array product.
Array at second place is the second array with the same number
of rows.
