random.test.data: Radmom data generator

In lctools: Local Correlation, Spatial Inequalities, Geographically Weighted Regression and Other Tools

Description

Generates datasets with random data for modelling including a dependent variable, independent variables and X,Y coordinates.

Usage

random.test.data(nrows = 10, ncols = 10, vars.no = 3, dep.var.dis = "normal", 
                xycoords = TRUE)

Arguments

nrows	an integer referring to the number of rows for a regular grid
ncols	an integer referring to the number of columns for a regular grid
vars.no	an integer referring to the number of independent variables
dep.var.dis	a character referring to the distribution of the dependent variable. Options are "normal" (default), "poisson", and "zip"
xycoords	a logical value indicating whether X,Y coordinates will be created (default) or not.

Details

The creation of a random dataset was necessary here to provide examples to some functions. However, random datasets may be used in simulation studies.

Value

a dataframe
