Linear Regression
Command: LinRegTTest
Description: This command treats two groups of data as paired variables (
of least squares is used to determine the most appropriate pair for the
coefficients of the regression formula
correlation coefficient and
relationship between
b =
a
: regression constant term (
b
: regression coefficient (slope)
n
: sample size (
r
: correlation coefficient
2
r
: coefficient of determination
Command Syntax
