The matlab help function of the program makes use of the spreadsheet that are usually available in most of the computers. All you need to do is to open this spreadsheet and enter your values. It also allows you to select the cells with certain values or labels. The cell or label that you have chosen will be highlighted in the help section and make it easy for you to determine what should be entered or changed. You can then choose to go to a particular help page or make use of the matlab help online.
You can also use the function to enter data in several ways, such as the average value, median value, range, standard deviation, and much more. There is also a help function that makes it possible for you to determine whether a median value falls within a range. This helps you make it possible for you to know what kind of error would be expected in the data. It also helps you determine how robust your statistical method is, based on the data that you have entered in the spreadsheet.
The help function in matlab is very convenient for students who want to know how much the average of their grades is over the course of the academic year. This help function will provide you with the estimated GPA, which you can then plot in the chart that you have created using the matlab spreadsheet. You can also plot the normal mean, the standard deviation, and other factors that you want to include in the plot. There is also a probability density function that can be used in the plot and makes it possible for you to see what kind special info of probability is associated with a given value. The normal distribution is a well-known average mean that is widely used by statisticians to express the value of a variable in a probability-like distribution.
There is also help function for multiple regression analysis in matlab. The regression functions allow you to evaluate the effect of several independent variables simultaneously in the model. This helps you evaluate the results from the model. You can evaluate the effect of the independent variables separately as well as the effect of each other on the dependent variable.
When it comes to interpreting the results from the regression analysis matlab help provides formula that can be conveniently used by the analyst. The help function in matlab calculates the mean square error and standard deviation of the estimates. These values are included in the data set that you are evaluating for your regression analysis. These values should be included in the plot as well, together with the corresponding confidence interval around the estimate.
Other useful features in matlab that can be very helpful for the student are to help objects. These help objects help you examine relationships among variables that are not linear and are not normally distributed. For example, if the data that you are working with is normally distributed and you plot the data logarithmically, then you will find that the fitted line will have a very high slope. By plotting logarithmic data without help objects, you will get a very steep slope. By using help objects you can get a more appropriate slope for your plot.
Another feature that you should take full advantage of is forecasting capabilities. If you want to predict what the result of a certain event will be, then it would be best if you could plot the data logarithmically. A linear estimator can only work in a finite number of cases and can therefore be relatively faulty, whereas the forecasting capability of matlab help objects allows you to predict what the outcome of a certain event will be based on prior information.
Summing up, matlab has some really cool features that can be extremely useful for the analyst who needs to plot a few data sets or a number of probability estimates. However, do not try to over use matlab help function to make your estimates too robust. It can lead to serious problems. Use help objects wisely to reduce the risk that your estimates will be too sensitive to other variables.
