DetSlope: Determine slope for the log(y) and x regression manually
Description
You choose a slope for terminal half-life.
Usage
DetSlope(x, y, SubTitle="", sel.1=0, sel.2=0)
Value
R2
R-squared
R2ADJ
adjusted R-squared
LAMZNPT
number of points used for the slope
LAMZ
negative of the slope, lambda_z
b0
intercept of the regression line
CORRXY
correlation of log(y) and x
LAMZLL
earliest x for lambda_z
LAMZUL
last x for lambda_z
CLSTP
predicted y value at the last point, predicted concentration for the last time point
Arguments
x
vector values of x-axis, usually time
y
vector values of y-axis, usually concentration
SubTitle
subtitle to be shown on the plot
sel.1
default index of the first element to use
sel.2
default index of the last element to use

Details
Sometimes BestSlope cannot find terminal slope satisfactorily. Then you can use this function to choose manually. It returns the same format result with BestSlope with an attribute indicating used points.
