I have a question. When I draw a heatmap, I see Heatmap - Transform - Standardize. Then, sometypes of normalized values come out. How are these normalized values calculated? I tried (value-average)/average, but it is not the same. Please let me know. Column Myl1 has these number 20; 17; 26 ; 67; 44; 39; 46; 20; 14 After Heatmap - Transform - Standardize; -0.7125; -0.88275; -0.37201; 1.95465; 0.67945; 0.36571; 0.76294; -0.7125; -1.05299

Normalize and Standardize are two different methods of rescaling data. Standardize is calculated by:
Xnew=(X-Xm)/Xsd)
Xnew: Standardized value X: Value Xm: The dataset mean Xsd: The dataset standard deviation
