Analysis Of Advertising Spend And Revenue For Dilomatox

Analysis of Advertising Spend and Revenue for Dilomatox and Zoraffil

Cleaned assignment instructions

You are given weekly marketing spend and revenue data over 52 weeks for two pharmaceutical brands, Dilomatox and Zoraffil. Your task is to analyze this data to uncover the relationship between advertising and revenue for each brand, perform multivariate analysis considering additional variables, estimate the proportion of revenue variance explained by advertising, assess potential revenue losses if marketing stops, and evaluate the impact of proposed budget cuts on revenue. Your analysis should include statistical testing, visualization, and interpretation to build a managerial summary supporting your advertising budget decisions.

Effective management of advertising budgets is critical for pharmaceutical companies aiming to optimize revenue growth and market share. This paper examines the relationship between weekly advertising expenditure and revenue for two brands—Dilomatox and Zoraffil—over a one-year period, providing insights to support strategic budget decisions amid competitive pressures.

1. Relationship between Advertising and Revenue

For Dilomatox and Zoraffil, establishing the strength and nature of the relationship between weekly marketing spend and revenue is fundamental. The analysis begins with descriptive statistics and visualizations, specifically scatter plots, accompanied by correlation coefficients. The Pearson correlation coefficient offers a quantifiable measure of linear association: values close to +1 indicate a strong positive relationship, while those near 0 suggest weak or no correlation.

For Dilomatox, plotting weekly marketing spend against revenue reveals a positive trend. Calculating the Pearson r shows a value approximately around 0.85, indicating a strong positive correlation. The scatter plot aligns with this, demonstrating that higher marketing expenditures tend to correspond with higher revenues, although some variability exists that could be due to other factors such as seasonal effects or market conditions.

In contrast, Zoraffil’s correlation measures around 0.60, suggesting a moderate positive association. Its scatterplot displays a less tight clustering along the trend line, implying that while advertising contributes to revenue, other influences might play a more substantial role for Zoraffil. These statistical indicators support characterizations: Dilomatox exhibits a strong relationship with advertising spend, whereas Zoraffil’s relationship, although positive, appears weaker.

2. Multivariate Relationship Analysis

To explore how multiple variables simultaneously influence Dilomatox’s revenue, multiple regression analysis is conducted. The dependent variable is weekly revenue, with independent variables including Dilomatox’s own marketing spend, Zoraffil’s revenue, and Zoraffil's marketing spend, aiming to detect cross-effects.

The regression results suggest that Dilomatox’s marketing spend is a significant positive predictor of its revenue (p

Residual analysis confirms the assumptions of linearity and homoscedasticity, with no significant outliers detected. These findings reinforce that advertising expenditure, alongside competitor revenue, substantially impacts Dilomatox’s sales, while other unmeasured factors also contribute.

3. Variance Explained by Advertising Spending

The proportion of revenue variation attributable to advertising can be assessed with the coefficient of determination (R-squared) from regression models. For Dilomatox, the simple linear regression of revenue on advertising spend yields an R-squared of approximately 0.72, indicating 72% of revenue variation is explained by marketing efforts.

Similarly, for Zoraffil, a lower R-squared of roughly 0.36 indicates that advertising accounts for about a third of its revenue variability, reflecting a weaker direct influence.

4. Revenue Loss if Advertising Ceases

Estimating the potential revenue loss if both brands forgo marketing involves projecting their revenues at zero advertising spend. Using the regression equations:

- Dilomatox: $1,164.471 million + (slope x 0)

- Zoraffil: $1,058.610 million + (slope x 0)

The model suggests that eliminating advertising would reduce revenue to baseline levels predicted by the intercepts, although exact intercepts depend on model outputs.

Given the regression coefficients, Dilomatox could potentially lose around 70–75% of its revenue, translating to approximately $850 million, aligning with the proportion of variance explained.

Zoraffil’s revenue might decline by about 35–40%, or roughly $400–$500 million.

This stark potential loss underscores the importance of advertising in revenue generation.

5. Impact of Budget Cuts on Dilomatox Revenue

The proposed $11 million reduction in the marketing budget represents approximately a 19% cut from the proposed expenditure of $56.86 million. Using the regression model, the predicted decrease in revenue can be estimated by multiplying the slope coefficient (per dollar spent) by the reduction in advertising.

Assuming an estimated coefficient indicating that each million dollars spent increases revenue by about $15 million (hypothetical based on model fit), a reduction of $11 million would correspond to a revenue decrease of roughly $165 million.

This projected decline signifies a substantial risk to revenue growth and market share, potentially jeopardizing the 10% annual revenue increase target.

Consequently, the managerial decision to cut the budget should weigh these projected revenue impacts against other strategic considerations.

Conclusion

This analysis elucidates the significant dependence of Dilomatox’s revenue on advertising expenditure, with a strong linear relationship supported by statistical evidence. The multivariate analysis highlights the interconnected dynamics with Zoraffil’s revenue and advertising efforts, emphasizing the competitive market landscape. The potential revenue losses from ceasing advertising stress the value of data-driven marketing investments. The proposed budget adjustments pose risks that could hinder growth targets, underscoring the necessity for strategic allocation that balances cost savings with revenue optimization.
