lin.coef: Linear Coefficients

Description

Returns the slope and intercept for x predicting y

Usage

lin.coef(x, y, out = "both", nomiss = 0.8)

Arguments

x

A numeric vector of the same length as y

y

A numeric vector of the same length as x

out

A character vector specifying whether the result should return just the intercept ("int"), just the slope ("slope") or both ("both") which defaults to "both"

nomiss

A numeric between .00 and 1.00 specifying the proportion of x-y pairs required to be complete before NA is returned instead of the regression coefficients. The default of .80 means that if more than 20 percent of the x-y pairs are incomplete an NA will be returned.

Value

b0

intercept of the regression line from y predicted from x

b1

slope of the regression line frome y predicted from x

Details

This function is largely designed to increase computation efficiency for getting regression coefficients. For instance, this function is called by the Profile.reg function (see Profile.reg).

Examples

data(RSPdata)
	# Lets predict self reported extraversion from gender
lin.coef(RSPdata$ssex,RSPdata$sEXT)
	# confirm that these numbers match the results from lm()
lm(sEXT ~ ssex, data = RSPdata)
