fixparsoptd.mae {soptdmaeA}

Sets parametric values and initial design

Description

Creates a tcltk window that allow the users to set or fix values for the parametric combinations and initial optimal or near-optimal design to compute sequential optimal or near-optimal block or row-column designs.

Usage

fixparsoptd.mae(Optcrit)

Arguments

Optcrit

character, specifying the optimality criteria to be used. Optcrit takes the letter "A", "MV", "D" and "E" for A-, MV-, D- and E-optimal or near-optimal designs, respectively.

Details

fixparsoptd.mae creates a pop-up tcltk window that allow the users to set the parametric combinations and initial optimal or near-optimal designs to compute optimal or near-optimal block or row-column designs. The parameters include the number of treatments trt.N, number arrays blk.N, theta value theta, number of replications of the optimization procedure nrep, number of added treatments strt, number of added arrays sary and a button that allows users to insert initial optimal or near-optimal design des0 by typing into a pop-up sheet that will occur when clicking on the 'Insert' button. The users are not restricted to a specific dimension of the initial design, thus, the dimension of the initial design des0 can be 2 x blk.N or blk.N x 2. The default initial design des0 is a 3 x 2 loop/cyclic design.

Furthermore, on this window, the checkbox options that allow the users to choose whether or not they need to have the graphical layout of the resultant sequential optimal or near-optimal block or row-column design, to make a choice between the two design types (block design and row-column designs) and to print the summary of the resultant sequential optimal or near-optimal design on R-console directly are available.

After setting all the required parametric combinations and selecting the algorithm of interest, clicking on the search button on the set parametric combinations tcltk window, similar to the results that can be obtained when using the function soptdmaeA, the summary of the resultant sequential optimal or near-optimal design will be saved in the current working directory in .csv format. The graphical layout of resultant sequential optimal or near-optimal design together with that of the initial optimal or near-optimal design will also be displayed on R console.

Value

The fixparsoptd.mae function creates a pop-up tcltk window that allow the users to set the parametric combinations to compute sequential optimal or near-optimal block or row-column designs.
