Regression Analysis: StockPrice versus Sales(B)

The regression equation is

StockPrice = 15.64 + 4.441 Sales(B)

S = 11.2028 R-Sq = 33.6% R-Sq(adj) = 31.8%

As x increases y increases therefore there is a positive relationship between x and y. Outlier strong effects the graph of the regression line.

Regression Analysis: StockPrice versus EBITDA(B)

The regression equation is

StockPrice = 13.10 + 16.88 EBITDA(B)

S = 8.79860 R-Sq = 59.1% R-Sq(adj) = 58.0%

As x increases y increases, therefore there is a positive relationship between x and y. Outliers affect the graph of the regression line.

Regression Analysis: StockPrice versus Profit Margin

The regression equation is

StockPrice = 17.09 + 12.97 Profit Margin

S = 13.4077 R-Sq = 4.9% R-Sq(adj) = 2.4%

As x increases y increases between -0. 1 and 0.5 which shows no real pattern to the scatter plot. Therefore this is little or no relationship between x and y.

Regression Analysis: StockPrice versus Earning

The regression equation is

StockPrice = 7.166 + 5.977 Earning

S = 7.50264 R-Sq = 70.2% R-Sq(adj) = 69.4%

As x increases y increases revealing a pattern which indicates a strong relationship between x and y

Regression Analysis: StockPrice versus Equiv.(MMboe)

The regression equation is
