Statistical Modelling
Correlation
- Measures the degree which 2 variables are related, do not fit a line
- Sample Correlation Coefficient: R
- Carry out hypo testing on the SAMPLE correlation (R) to find out the POPULATION correlation (Rho)
- R is just an estimate of Rho
- Rho: The population correlation which measures the correlation of all possible pairs of observations from the 2 variables
- Carry out hypo testing on the SAMPLE correlation (R) to find out the POPULATION correlation (Rho)
- Sample Correlation Coefficient: R
- Measures the degree which 2 variables are related, do not fit a line
Regression
- Tries to create the best fit line
- Regression Model
- For a particular explanatory variable, e.g.. x=5 for the age=5, the response variables follows a normal distribution
- Conditional Mean
- The conditional mean is just the value when x=5..
- Conditional Standard Deviation
- Conditional Mean
- For a particular explanatory variable, e.g.. x=5 for the age=5, the response variables follows a normal distribution
