IT Lab Day5 Assignment


Assignment1

1. Find returns of NSE data of greater than 6 months having selected the 10th data point as start and 95th data point as end.

2. Find plot of that return.




Commands:

> z<-read.csv(file.choose(),header=T)

> Close<-z$Close
> Close
> Close.ts<-ts(Close)
> Close.ts<-ts(Close,deltat= 1/252)
z1<-ts(data=Close.ts[10:95],frequency=1,deltat=1/252) 
> z1.ts<-ts(z1)
> z1.ts
> z1.diff<-diff(z1)
> z2<-lag(Close.ts,K=-1)
> Returns<-z1.diff/z2
> plot(Returns,main=" Returns from 10th to 95th day of NSE Mid-cap Index ")
z3<-cbind(z1.ts,z1.diff,Returns)
> plot(z3,main=" Data from 10th-95th day ; Difference ; Returns")

Assignment2
 
 1-700 data is available, Predict the data from 701-850, use the GLM estimation using LOGIT Analysis for the same.

Commands:

> z<-read.csv(file.choose(),header=T)
> z1<-z[1:700,1:9]
> head(z1)
> z1$ed<-factor(z1$ed)
> z1.est<-glm(default ~ age + ed + employ + address + income, data=z1, family ="binomial")
> summary(z1.est)

> forecast<-z[701:850,1:8]
> forecast$ed<-factor(forecast$ed)
> forecast$probability<-predict(z1.est,newdata=forecast,type="response")
> head(forecast)
