        <para><function>DAVERAGE</function> function returns the average of the values in a list or database that match conditions specified.</para>
        <para><parameter>database</parameter> is a range of cells in which rows of related information are records and columns of data are fields. The first row of a database contains labels for each column.</para>
        <para><parameter>field</parameter> specifies which column is used in the function.  If <parameter>field</parameter> is an integer, for example 2, the second column is used. Field can also be the label of a column.  For example, ``Age'' refers to the column with the label ``Age'' in <parameter>database</parameter> range.</para>
        <para><parameter>criteria</parameter> is the range of cells which contains the specified conditions.  The first row of a <parameter>criteria</parameter> should contain the labels of the fields for which the criteria are for.  Cells below the labels specify conditions, for example, ``>3'' or ``<9''.  Equality condition can be given simply by specifying a value, e.g. ``3'' or ``John''.</para>
        <para>Each row in <parameter>criteria</parameter> specifies a separate condition. If a row in <parameter>database</parameter> matches a row in <parameter>criteria</parameter>, then that row is counted. Technically speaking, this a boolean OR operation between the rows in <parameter>criteria</parameter>.</para>
        <para>If <parameter>criteria</parameter> specifies more than one column, then each of the conditions in the specified columns must be true for the row in <parameter>database</parameter> to match. Technically speaking, this is a boolean AND operation between the columns in <parameter>criteria</parameter>.</para>

        <para><function>OPT_TIME_SWITCH</function> models the theoretical price of time switch options. (Pechtl 1995)</para>
        <para>The holder receives <parameter>a</parameter> * <parameter>dt</parameter> for each period dt that the asset price was greater than the strike price (for a call) or below it (for a put)</para>
        <para><parameter>call_put_flag</parameter> is 'c' or 'p' to indicate whether the option is a call or a put.</para>
        <para><parameter>spot</parameter> is the spot price of the underlying asset</para>
        <para><parameter>strike</parameter> is the strike price at which the option is struck</para>
        <para><parameter>a</parameter> is the amount received for each time period as discussed above</para>
        <para><parameter>time</parameter> is the maturity of the option in years</para>
        <para><parameter>m</parameter> is the number of time units the option has already met the condition</para>
        <para><parameter>dt</parameter> is the agreed upon discrete time period (often a day) expressed as a fraction of a year</para>
        <para><parameter>rate</parameter> is the risk annualised free rate of interest</para>
        <para><parameter>cost_of_carry</parameter> is the leakage in value of the underlying asset, for common stocks, this would be the dividend yield</para>

        <title>Description</title>
        <para><function>SYD</function> function calculates the sum-of-years digits depreciation for an asset based on its cost, salvage value, anticipated life and a particular period. This method accelerates the rate of the depreciation, so that more depreciation expense occurs in earlier periods than in later ones. The depreciable cost is the actual cost minus the salvage value. The useful life is the number of periods (typically years) over with the asset is depreciated.</para>
        <para>The Formula used for sum-of-years digits depreciation is:</para>
        <para>Depreciation expense =</para>
        <para>     ( <parameter>cost</parameter> - <parameter>salvage_value</parameter> ) * (<parameter>life</parameter> - <parameter>period</parameter> + 1) * 2 / <parameter>life</parameter> * (<parameter>life</parameter> + 1).</para>

        <para>=<function>SYD</function>(5000, 200, 5, 2) which returns 1,280.00.</para>

        <para><function>SIMTABLE</function> returns one of the values in the given argument list depending on the round number of the simulation tool. When the simulation tool is not activated, <function>SIMTABLE</function> returns <parameter>d1</parameter>.</para>
        <para>With the simulation tool and the <function>SIMTABLE</function> function you can test given decision variables. Each <function>SIMTABLE</function> function contains the possible values of a simulation variable. In most valid simulation models you should have the same number of values <parameter>dN</parameter> for all decision variables.  If the simulation is run more rounds than there are values defined, <function>SIMTABLE</function> returns #N/A! error (e.g. if A1 contains `=<function>SIMTABLE</function>(1)' and A2 `=<function>SIMTABLE</function>(1,2)', A1 yields #N/A! error on the second round).</para>
        <para>The successive use of the simulation tool also requires that you give to the tool at least one input variable having RAND() or any other RAND<distribution name>() function in it. On each round, the simulation tool iterates for the given number of rounds over all the input variables to reevaluate them. On each iteration, the values of the output variables are stored, and when the round is completed, descriptive statistical information is created according to the values.</para>

        <para><function>LOGFIT</function> returns an array having five columns and one row. `Sign' is given in the first column, `a', `b', and `c' are given in columns 2 to 4. Column 5 holds the sum of squared residuals.</para>

        <para>You can use the above formula</para>

        <para>If <parameter>stat</parameter> is TRUE, extra statistical information will be returned which applies to the state AFTER transformation to z. Extra statistical information is written below m and b in the result array.  Extra statistical information consists of four rows of data.  In the first row the standard error values for the coefficients m, b are represented.  The second row contains the square of R and the standard error for the y estimate. The third row contains the F-observed value and the degrees of freedom.  The last row contains the regression sum of squares and the residual sum of squares.The default of <parameter>stat</parameter> is FALSE.</para>

        <para><function>TRIMMEAN</function> returns the mean of the interior of a data set. <parameter>ref</parameter> is the list of numbers whose mean you want to calculate and <parameter>fraction</parameter> is the fraction of the data set excluded from the mean. For example, if <parameter>fraction</parameter>=0.2 and the data set contains 40 numbers, 8 numbers are trimmed from the data set (40 x 0.2), 4 from the top and 4 from the bottom of the set.</para>
