Real Estate Price Prediction
Execute by Neha Raut
Problem Statement:
Price of a property is one of the most important decision criterion when people buy homes. Real state firms need to be consistent in their pricing in order to attract buyers . Having a predictive model for the same will be great tool to have , which in turn can also be used to tweak development of properties , putting more emphasis on qualities which increase the value of the property
Aim
To Build a predictive model and predict the accurate prices of the proterties.
The evalution metric will be RMSE.Data Information:
There exist two datasets, housing_train.csv and housing_test.csv . We will use data housing_train to build predictive model for response variable “Price”. Housing_test data contains all other factors except “Price” which we can use for testing purpose.
Data dictionary:
Variables : Type :: Definition Suburb : categorical :: Which subsurb the property is located in
Address : categorical :: short address
Rooms : numeric :: Number of Rooms
Type : categorical :: type of the property
Price : numeric :: This is the target variable, price of the property
Method : categorical :: method for selling
SellerG : categorical :: Name of the seller
Distance : numeric :: distance from the city center
Postcode : categorical :: postcode of the property
Bedroom2 : Numeric :: numbers of secondary bedrooms (this is different from rooms)
Bathroom : numeric :: number of bathrooms
Car : numeric :: number of parking spaces
Landsize : numeric :: landsize
BuildingArea : numeric :: buildup area
YearBuilt : numeric :: year of building
CouncilArea : numeric :: council area to which the propery belongs
Methodology:
We will build a linear regression model to predict the response variable “Price”
1.Imputing NA values in the datasets.
2.Data Preparation.
3.Model Building.
4.Perfomance measurement of the model.
5:Predicting Real Estate Prices for the final Test Dataset.
Step 1: reading File
Combining both train n test datasets prior to data preparation.
loading library dplyr
library(dplyr)Read train and test datasets:
re_train=read.csv("housing_train.csv",stringsAsFactors = FALSE,header = T)
#7536 obs,16 variables
re_test=read.csv("housing_test.csv",stringsAsFactors = FALSE,header = T) #1885
#1885 obs,15 variablesStep 2: Step 2:Data Preparation
Combining both train n test datasets prior to data preparation.
Before combining however , we’ll need some placeholder column which we can use to differentiate between observations coming from train and test data. Also we’ll need to add a column for response to test data so that we have same columns in both train and test. We’ll fill test’s response column with NAs.
re_test$Price=NA
re_train$data='train'
re_test$data='test'

re_all=re_all[!((is.na(re_all$Price)) & re_all$data=='train'), ]
for(col in names(re_all)){
if(sum(is.na(re_all[,col]))>0 & !(col %in% c("data","Price"))){
re_all[is.na(re_all[,col]),col]=mean(re_all[re_all$data=='train',col],na.rm=T)
}
}sum(is.na(re_all$data=='train'))## [1] 0Separating test and train from data(combination)
Lets separate our two data sets and remove the unnecessary columns that we added while combining them.
re_train=re_all %>% filter(data=='train') %>% select(-data)
re_test=re_all %>% filter(data=='test') %>% select(-data,-Price)Step 3: Model Building
We will use train_75 for linear regression model building and use train_25 to test the performance of the model thus built.
set.seed(2)
s=sample(1:nrow(re_train),0.75*nrow(re_train))
train_75=re_train[s,] #5652
train_25=re_train[-s,] #1884Lets build linear regression model on train_75 dataset.

## F-statistic: 85.75 on 133 and 5518 DF, p-value: < 2.2e-16All VIF values are under control.Now we look at the model summary , specifically p-values asscociated with the variables. We can drop variables with high p-values [ >0.05] one by one or we can use step function which drops vars based on AIC score one by one. Although the methodology is different but end result is generally similar due to both of them targetting vars which do not contribute towards explaning not very well.

## Residual standard error: 384700 on 5581 degrees of freedom
## Multiple R-squared: 0.6698, Adjusted R-squared: 0.6656
## F-statistic: 161.7 on 70 and 5581 DF, p-value: < 2.2e-16Thus linear regression model is successfully built.
Step 4.Perfomance measurement of the model.
Lets check the performance of the model on test_25 and calculate RMSE
PP_train_25=predict(LRF_75,newdata =train_25) #Predicted value
PP_train_25=round(PP_train_25,1)
class(PP_train_25)## [1] "numeric"##Correlation between actual and predicted values
actuals_preds <- data.frame(cbind(actuals=train_25$Price, predicteds=PP_train_25))
cor(train_25$Price,PP_train_25) #0.7984319## [1] 0.7991232#lets plot the real price vs predicted price for dataset test_25:
plot(train_25$Price,PP_train_25)
res=train_25$Price-PP_train_25 #(real value-predicted value)
#root mean square error is as follows
RMSE_test_25=sqrt(mean(res^2))
RMSE_test_25## [1] 382882.2#the passing criteria mentioned,was to have value >0.5 which we have successfuly crossed.Hence our model is good.
212467/RMSE_test_25## [1] 0.5549148lets create diagonostic plots for linearity:
library(ggplot2)d=data.frame(real=train_25$Price,predicted=PP_train_25)
ggplot(d,aes(x=real,y=predicted))+geom_point()
plot(LRF_75,which = 1) #gives residual vz fitted plot
plot(LRF_75,which = 2) #gives q-q-plot
plot(LRF_75,which = 3) #gives scale-location plot
plot(LRF_75,which = 4) #gives cooks distance
STEP 5:Predicting Real Estate Prices for the final Test Dataset.
As per the model thus built,we can now predict Prices for the Test dataset as follows:
PP_test_final=predict(LRF_75,newdata =re_test) #Predicted value
PP_test_final=round(PP_test_final,1)
class(PP_test_final)## [1] "numeric"write.csv(PP_test_final, "Neha_Raut_P1_Part2.csv",row.names = F)
