IModelling.MinI

Syntax

MinI(Inputs: Array): Variant;

Parameters

Inputs. Variable.

Description

The MinI method returns the minimum value among the points of the variable if it contains only integer values.

Comments

If more than one variable is specified in Inputs, the minimum values of corresponding variable points are calculated. For example, the minimum values of points of 2018 by all variables.

Variables in Inputs must be separated via comma.

A calculation period can be set for the method. To do this, use the IModelling.SetPeriod method, by specifying it at any place of input array.

To calculate the method without taking into account empty values, use the IgnoreMissing parameter by specifying it in any place of the input array. Available values of the parameter:

Use the IModelling.Min method to get minimum value of the variable containing not only integer values.

Example

Executing the example requires that the repository contains a modeling container with the MS identifier. This contains includes a model with the MODEL_D identifier that is calculated by the determinate equation method and contains more than one input variable.

The first input variable must contain only integer values.

Add links to the Metabase and Ms system assemblies.

    Model := ModelObj As IMsModel;
    Transf := Model.Transform;

    Determ := Formula.Method As IMsDeterministicTransform;
    // Get the first input variable
    Term := Determ.Operands.Item(0);
    Inp_1 := Term.TermToInnerText;
    // Get the second input variable
    Term := Determ.Operands.Item(1);
    Expr := Determ.Expression;
    Expr.References := "Ms";
    Expr.AsString := Term.TermToInnerText + "+MinI(" + Inp_1 + ")";
    If Expr.Valid
        Then ModelObj.Save;
        Else Debug.WriteLine(Model is not saved: error in formula);
    End If;
End Sub UserMinI;

After executing the example the model calculates values of the second input variable increased by the minimum value of the first input variable.

Example of Use in Expressions

Expression 1:

MinI({Brazil|BCA},{Peru|BCA})

Result: minimum value of corresponding obesrvations of the Brazil|BCA and Peru|BCA series. If any of time series contains the real values, an error occurs.

Use: it can be used in formulas of cross functional expression editor in any platform tool where it is available.

Expression 2:

MinI(X1, SetPeriod(2000,2010), false)

Result: minimum value of points of the X1 factor taking into account empty values at the period of 2000-2010.

Use: it can be used in model formulas of modeling container based on variables.

Expression 3:

MinI(1, 2, 3, 4)

Result: 1.

Application: it can be used in any expressions.
