If two variables are correlated, it does not imply that one variable causes the changes in another variable. The famous expression “correlation does not mean causation” is crucial to the understanding of the two statistical concepts. Correlation and CausationĬorrelation must not be confused with causality. A thorough understanding of this statistical concept is essential to successful portfolio optimization. One of the primary applications of the concept in finance is portfolio management. The variables tend to move in the same direction (i.e., when one variable increases, the other variable also increases). The variables do not have a relationship with each other.

The variables tend to move in opposite directions (i.e., when one variable increases, the other variable decreases). The coefficient can take any values from -1 to 1. The correlation coefficient is a value that indicates the strength of the relationship between variables. Using a scatterplot, we can generally assess the relationship between the variables and determine whether they are correlated or not. The fit of the data can be visually represented in a scatterplot. The measure is best used in variables that demonstrate a linear relationship between each other. StatPlus:mac uses Pearson Product-Moment to compute pairwise correlations between each pair of variables and laces them in a table.A correlation is a statistical measure of the relationship between two variables. StatPlus:mac provides ANOVA (one, two and three way) GLM models and Latin squares analysis. Once the graph is embedded you have access to the Excel formatting options, which unfortunately are now looking rather dated (this is of course an Excel issue). I know you can add these within Excel but it would be useful to do this when you create the graph.

This is fine but since you probably have a workbook with data it would be nice to have the option to choose the workbook to open. There is no added set of menu items in Excel, instead you need to switch between an open Excel workbook and StatPlus:mac.Īt first the need to switch between applications seems rather clunky but after a while using Appletab becomes second nature.Īfter starting StatPlus:mac one of the menu options is Launch Microsoft Excel, this opens a blank workbook. The Help system is excellent and gives detailed information.Īctually it is a great demonstration of what is possible with Applescript.
