You use the Simulation menu to set the options for the simulation process, and also to start the simulation process. The menu contains the following options:
You activate this option to specify the settings for the simulation process.
The first parameter that can be set, is the type of output. You can either produce a histogram of the sampling distribution of the estimator or 95%-confidence intervals.
The second parameter (Simulations) that can be set is the number of simulations. The default value is 1000, but you can set any number between 2 and 1000.
The third parameter (Scale) controls the horizontal scaling of the x-axis in the histogram of the distribution of the estimator. By setting a sample size, the lowerbound of the x-axis is taken to be the smallest value the estimator can assume for that sample size. Likewise, the upperbound is taken to be equal to maximum value of the estimator for this sample size. By increasing the value of this parameter, the lowerbound is increased and the lower bound decreased. It also possible to directly enter a lowerboud and upperbound of the x-axis.
The fourth parameter (Compression) controls the amount of vertical compression in the histogram. You can select a value from 1 to 4. A value of 1 means no compression. A value of 4 will compress the histogram by a factor 4.
After having set the simulation options, you start the simulation process by activating this option.
The vertical line indicates the population mean of the target variable to be estimated.
The simulation window contains a number of buttons:
By clicking on Next, the program will process the next sample of the simulation. This is the step-wise way of carrying out the simulation.
By clicking on Automatic, you switch to continuous simulation. All samples are processed one after the other without the possibility of interruption.
After the simulation has been completed, you press Statistics to get a numerical overview of the simulation results.
You can save the graph in a bitmap file by clicking on the Save button.
