#### Description

The random variates are drawn from a skew-normal distribution with shape parameter `𝛼`.

#### Note

The mean of a skew-normal distribution with location parameter `𝜉`=0 is not 0. The standard deviation of a skew-normal distribution with scale parameter `𝜔`=1 is not 1. The skewness of a skew-normal distribution is in general not `𝛼`. If `𝜔` < 0, `RANDSNORM` returns #NUM!

#### Arguments

`d1`: first value

#### 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.

#### 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.

    JIS(text)

#### Arguments

`text`: original text

#### Description

`JIS` converts half-width katakana and ASCII characters to full-width equivalent characters, copying all others.

The distinction between half-width and full-width characters is described in http://www.unicode.org/reports/tr11/.

#### Note

While in obsolete encodings `JIS` used to translate between 1-byte and 2-byte characters, this is not the case in UTF-8.

#### Description

This array function returns the Fourier or inverse Fourier transform of the given data sequence.

The output consists of one column of complex numbers if `Separate` is false and of two columns of real numbers if `Separate` is true.

If `Separate` is true the first output column contains the real parts and the second column the imaginary parts.

#### Note

If `Sequence` is neither an n by 1 nor 1 by n array, this function returns #VALUE!

`INTERPOLATION`

`INTERPOLATION`

#### Arguments

`abscissae`: abscissae of the given data points

`ordinates`: ordinates of the given data points

`targets`: abscissae of the interpolated data

`interpolation`: method of interpolation, defaults to 0 ('linear')

#### Description

The output consists always of one column of numbers.

Possible interpolation methods are:

0: linear;

1: linear with averaging;

2: staircase;

3: staircase with averaging;

4: natural cubic spline;

5: natural cubic spline with averaging.

#### Note

The `abscissae` should be given in increasing order. If the `abscissae` is not in increasing order the `INTERPOLATION` function is significantly slower. If any two `abscissae` values are equal an error is returned. If any of interpolation methods 1 ('linear with averaging'), 3 ('staircase with averaging'), and 5 ('natural cubic spline with averaging') is used, the number of returned values is one less than the number of targets and the target values must be given in increasing order. The values returned are the average heights of the interpolation function on the intervals determined by consecutive target values. Strings and empty cells in `abscissae` and `ordinates` are ignored. If several target data are provided they must be in the same column in consecutive cells.

#### Description

If an interpolation method is used, the number of returned values is one less than the number of targets and the targets values must be given in increasing order.

2: Hahn (cosine window)

3: Welch (parabolic window)
