In kevinlzheng/RegR: Collective Functions to Perform Generalized Linear Model Graphs

Description

This function performed changing point analysis similar to rpart package.However, pvalues are computed in this function, as well as confidence intervals.

Usage

chngp.nonpar(data, xvar, yvar, nindex = NULL, num = T, bin = F)

Arguments

data	A input data frame, default to be NULL,
xvar	x variable, either column name or index value; stressor variable
yvar	y variable, either column name or index value; response variable
nindex	the column to define bins
num	boolean variables to determine if Gausian or binomial function
bin	binomial

Value

Returns . sum((x-xmean)^2)) = sum(x^2)- (sum(x))^2/length(x)

Examples

set.seed(1)
n = 50
x <- rlnorm(n) + 1:n
x <- (x - min(x))/max(x)
y <- n + 1:n + (rnorm(n))*0.2*n
pvalue <- chngp.nonpar(data, xvar, yvar,nindex=NULL, num = T)
