R Documentation

Fit linear regression, return parameters and p-values

Description

This function fits a linear regression and returns the parameters, including p-values from Anova. Here the vector 'y' (scalar response or dependent variable, ie the value that should get estimated) will be estimated according to 'dep' (explanatory or independent variable). Alternatively, 'dep' may me a matrix where 1st column will be used as 'dep and the 2nd column as 'y'.

Usage

linRegrParamAndPVal(
  dep,
  y = NULL,
  asVect = TRUE,
  silent = FALSE,
  debug = FALSE,
  callFrom = NULL
)

Arguments

`dep`	(numeric vector, matrix or data.frame) explanatory or dependent variable, if matrix or data.frame the 1st column will be used, if 'y'=`NULL` the 2nd column will be used as 'y'
`y`	(numeric vector) independent variable (the value that should get estimated based on 'dep')
`asVect`	(logical) return numeric vector (Intercept, slope, p.intercept, p.slope) or matrix or results
`silent`	(logical) suppress messages
`debug`	(logical) additional messages for debugging
`callFrom`	(character) allow easier tracking of messages produced

Value

numeric vector (Intercept, slope, p.intercept, p.slope), or if asVect==TRUE as matrix (p.values in 2nd column)

Examples

linRegrParamAndPVal(c(5,5.1,8,8.2),gl(2,2))
