r2b: computing a norm value for the segment from point k1 to k2-1

In boshek/limnotools: A set of tools and commands to utilize high resolution water profile data

Description

A -[REAL] coefficient of linear regression (will zero if K1=0) (y=Ax+B), B -[REAL] coefficient of linear regression, R2B -[REAL] norm of the segment (maximum "distance" measured perpendicular to the regression line)

Usage

r2b(k1, k2, x, y)

Arguments

k1	[INTEGER] start point
k2	[INTEGER] end point+1
x	[REAL(?)] input x-axis array (predictor)
y	[REAL(?)] input y-axis array (response)

Value

A -[REAL] coefficient of linear regression (will zero if K1=0) (y=Ax+B), B -[REAL] coefficient of linear regression, R2B -[REAL] norm of the segment (maximum "distance" measured perpendicular to the regression line)

Examples

ni <- c( 1, 201, 402 )
i <- 1
k1 <- ni[i]
k2 <- ni[i+1]


r2b(k1, k2, y=t11$temper, x=t11$depth)
