hedIndex {hpiR}

Create a full index object by hedonic approach

Description

Wrapper to create index object via entire hedonic approach

Usage

hedIndex(trans_df, dep_var = NULL, ind_var = NULL, hed_spec = NULL,
  ...)

Arguments

trans_df

data.frame of transactions

dep_var

default = NULL; Dependent variable in hedonic model

ind_var

default = NULL; Independent variables in the hedonic model

hed_spec

default = NULL; Full hedonic model specification

...

Additional Arguments

Value

'hpi“ object. S3 list with:

data

'hpidata' object

model

'hpimodel' object

index

'hpiindex' object

Further Details

Additional argument need to provide necessary argument for create 'hpidata' objects if the 'trans_df' object is not of that class.

Examples

 # Load data
 data(ex_sales)

 # Create index with raw transaction data
 hed_index <- hedIndex(trans_df = ex_sales,
                       periodicity = 'monthly',
                       min_date = '2010-06-01',
                       max_date = '2015-11-30',
                       adj_type = 'clip',
                       date = 'sale_date',
                       price = 'sale_price',
                       trans_id = 'sale_id',
                       prop_id = 'pinx',

                       max_period = 48,
                       dep_var = 'price',
                       ind_var = c('tot_sf', 'beds', 'baths'),
                       smooth = FALSE)
