Confidence Interval Estimate of the Correlation Coefficient for Age and Systolic Blood Pressure of 20, 30 and 50 Individuals
Onyedikachi O. John · Journal of Advances in Mathematics and Computer Science · 2019
A formula for the confidence interval of correlation coefficient based on the Fishers’ z-transformation, (where z = arctanh(r) and is used to convert the skewed distribution of sample correlation, r to a normal distribution) was applied to the age and systolic blood pressure of 2...
