Objectives
To calculate beta of RELAXO and find its significance using regression analysis with NIFTY50.

Data collection
The closing price data of Nifty50 and RELAXO was taken from www.nseindia.com for the time period 1st March 2019 to 28th Feb 2020. From the available data, the closing rates of all the Fridays in the year was sorted to find out weekly returns for both Nifty as well as PEL. Then the weekly returns was calculated for both by using formula – Weekly Return= (C3-C2)/(C2*100) where, C3 is present week closing price and C2 is the previous week closing price. Once the data is calculated, weekly return column for NIFTY50 is considered as “X” variable and the weekly returns column for RELAXO is considered as “Y” variable.

The Model and formulas used are:
Y = a +bX
X ̅ =∑X/N
Y ̅=∑Y/N
x = X – X ̅
y = Y – Y ̅
b=∑xy/∑(x)^2
a= Y ̅- bX ̅
e = Y – Y ̅
Variance of error=(σe)^2 =∑e^2/N-K
S.E of b = √ ((σe)^2 /∑x^2)
t stat of b = b/ S.E of b
TSS=ESS+RSS
ESS = (b^2)*(∑x^2)
RSS = ∑e^2
R^2 = ESS/TSS
F = Mean ESS/Mean RSS

Data analysis
Using the Regression Add-on in Microsoft Excel Data Analytics tool we get following values:
R Square= 0.032
a= 0.269
b = 0.723
N (Observations) = 50
F = 1.608
Therefore, formulating below question:
Y = 0.269- 0.723X
(1.2681)

Result
The above equation tells us the relationship between “Y” and “X”, that is Demand and Price. If price raises by unit, demand raises by 0.723 units. Positive sign says that, there is reverse relationship. Means if price rises demand rises, similarly if price falls then demand also falls. Figure In bracket is t-stat for “b”. b value for which is more than 0.05 so “b” is statistically significant at 5%. R2 = 0.032, which means 32% Y is explained by X. 68% error or other variables aren’t in the models. F is 1.608. The P value for which is more than 0.05, overall model is statistically significant at 5%.

Conclusion
Price is significant and overall model is significant but error will be 68%.
