calc_layer_scales: calc_layer_scales

In ATFutures/nyped: Model of pedestrian flows throughout New York City

Description

Calculate relative scales of contributions of each flow layer to final model of pedestrian flows generated by successive calls to build_ped_model.

Usage

calc_layer_scales(data_dir, model = "final")

Arguments

data_dir	The directory in which data are to be, or have previously been, downloaded.
model	Default "final" uses the final model of layers reduced only to those with significance less than 'sig_model' in build_ped_model, otherwise the full model with potentially less significant layers is used.

Value

A ‘data.frame' with six columns of (1) ’model' with the layer names; (2) 'estimates' holding the estimates for each layer from the multiple linear regression model; (3) 'full_rel' with the relative scaling coefficient for the contribution of each layer weighted by the full flow layers; (4) 'ped_rel' with equivalent values weighted by values at pedestrian count stations only; (5) 'full_abs' with the absolute scaling coefficient for each layer weighted by full flow layers; and (6) 'ped_abs' with equivalent values weighted by values at pedestrian count stations only.
