Computing and comparing correlation and regression coefficients using a pocket calculatorPrograms suitable for pocket calculators using reverse Polish notation are described. Program 1 computes regression coefficients, correlation coefficient, and standard error of estimate for paired data. Program 2 performs ...
which measures a linear dependence between two variables (x and y). It’s also known as aparametric correlationtest because it depends to the distribution of the data. It can be used only when x and y are from normal distribution. The plot of y = f(x) is named thelinear regression...

Effect size calculations relied on SPSS (semipartial correlation (sr)—small ≥ 0.1, medium ≥ 0.24, large ≥ 0.37) or an online calculator (d—small ≥ 0.2, medium ≥ 0.5, large ≥ 0.8) [15]. Correlation and multiple regression analysis Categories of CS were...
The tests used were intraclass correlation coefficient, Mann-Whitney test, and univariate linear regression analysis. Results When the patients were classified according to the cutoff point defined as determining a high risk of a major osteoporosis fracture (≥20 %), 0.75 % were defined as high ...
