I need help understanding how to interpret a linear regression using a Hedonic Model. I have a just of what it is but I am not conveying it correctly.
Here is the data I had to do a regression: B is Beta by the way
where PH = price of the house ($) B1BEDS = bedrooms (number) B2BATHS = bathrooms (number) B3SQFT = area of the house (feet squared) B4LOT = area of the lot (feet squared) B5DISTANCE = distance from the lake (feet) B6SECCHI = lake water clarity (meters) B7SURFCAREA = surface area of the lake (kilometers squared)
The question is
In hedonic regression methods, heterogeneous goods can be
described as a function of their attributes or characteristics. In
your example, the housing context, these attributes or
characteristics may contain both the structure of the asset and the
location of the asset.
The hedonic method may be used for the purpose of obtaining the
estimates of the willingness to pay for, or marginal cost of
producing, the different characteristics.
The most popular specification of the model is the log-lin
form
pi = exp(a+xb)
ln(pit) = b0 + b1x +
uit
Your question does not specify the functional form, but it seems it is a fully linear form. That is also fine and the interpretations that you have made are also correct.
But, if we have the semi-log form, and
b2, b3 and b6 are the coefficients
of number of bathrooms, area of the house, and the lake water
clarity.
A unit change in the number of bathrooms will increase the price of
the house by [exp(b2) - 1] %
A unit change in the area of the house will increase the price of
the house by [exp(b3) - 1] %
A unit change in the clarity of water by a meter, will increase the
marginal willingness to pay for clean water by [exp(b6)
- 1] %

A real estate study was conducted in the school district of
Alhambra to determine what variables influenced the market value of
a house (denoted by PRICE in $1,000s). Four possibly important
variables – HOUSE (the house size in 1,000s of square feet), LOT
(the lot size in 1,000s of square feet), BED (the number of
bedrooms), BATH (the number of bathrooms), and AGE (the age of the...
I need help putting this into Excel as I'm not sure how to find answers to these questions. I've only put part of the table in, otherwise it's too long. Any help is greatly appreciated! A) Develop the following simple linear regression models to predict the sale price of a house based upon a 90% level of confidence. A1) Write the regression equation for each model. A2) Sale price based upon square feet of living area. A3) Sale price based...
I have this project, I would like to hace an idea of how to do

Thank you in advance!
This is just the sample budget of how to designed!
