@{field} is a string or integer specifying which field is to be used. If @{field} is an integer n then the nth column will be used. If @{field} is a string, then the column with the matching label will be used.
@{criteria} is a range containing conditions. The first row of a @{criteria} should contain labels. Each label specifies to which field the conditions given in that column apply. Each cell below the label specifies a condition such as ">3" or "<9". An equality condition can be given by simply specifying a value, e. g. "3" or "Jody". For a record to be considered it must satisfy all conditions in at least one of the rows of @{criteria}.

@DESCRIPTION=SIMTABLE 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, SIMTABLE returns @{d1}.
With the simulation tool and the SIMTABLE function you can test given decision variables. Each SIMTABLE function contains the possible values of a simulation variable. In most valid simulation models you should have the same number of values @{dN} for all decision variables.  If the simulation is run more rounds than there are values defined, SIMTABLE returns #N/A! error (e.g. if A1 contains `=SIMTABLE(1)' and A2 `=SIMTABLE(1,2)', A1 yields #N/A! error on the second round).
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.

@FUNCTION=LOGFIT
@SHORTDESC=logarithmic least square fit (using a trial and error method)
@SYNTAX=LOGFIT(known_ys,known_xs)
@ARGUMENTDESCRIPTION=@{known_ys}: known y-values
@{known_xs}: known x-values
@DESCRIPTION=LOGFIT function applies the “least squares” method to fit the logarithmic equation y = a + b * ln(sign * (x - c)) ,   sign = +1 or -1 to your data. The graph of the equation is a logarithmic curve moved horizontally by c and possibly mirrored across the y-axis (if sign = -1).
LOGFIT 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.
@NOTE=An error is returned when there are less than 3 different x's or y's, or when the shape of the point cloud is too different from a ``logarithmic'' one. You can use the above formula = a + b * ln(sign * (x - c)) or rearrange it to = (exp((y - a) / b)) / sign + c to compute unknown y's or x's, respectively.  This is non-linear fitting by trial-and-error. The accuracy of `c' is: width of x-range -> rounded to the next smaller (10^integer), times 0.000001. There might be cases in which the returned fit is not the best possible.

@{affine}: if true, the model contains a constant term, defaults to true
@{stat}: if true, extra statistical information will be returned; defaults to FALSE
@DESCRIPTION=LOGREG function transforms your x's to z=ln(x) and applies the “least squares” method to fit the linear equation y = m * z + b to your y's and z's --- equivalent to fitting the equation y = m * ln(x) + b to y's and x's. LOGREG returns an array having two columns and one row. m is given in the first column and b in the second. 
Any extra statistical information is written below m and b in the result array.  This extra statistical information consists of four rows of data:  In the first row the standard error values for the coefficients m, b are given.  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 @{stat} is FALSE.
@NOTE=If @{known_ys} and @{known_xs} have unequal number of data points, this function returns a #NUM! error.
