Calculate Variance Inflation Factor
Normally, variance is the difference between an expected and actual result. In statistics, the variance is calculated by dividing the square of the deviation about the mean by the number of the population. To calculate the deviation from the mean, the difference of each individual value from the...

Another way of enhancing R-squared is addressingmulticollinearity. Multicollinearity is when independent variables are highly correlated with each other. However, they can distort coefficient estimates and reduce the accuracy of the model. Techniques like variance inflation factor analysis or principal compon...
The coefficient of determination indicates the percentage that the independent variable can explain the variance in the dependent variable. For example, it can show the relationship between inflation and interest rates, because a significant inflation may trigger higher interest rates. Many organizations ...

When calculating YoY growth, it’s important to factor in external elements like inflation and seasonality, which can significantly skew your results. Adjusting for seasonality allows for a more accurate comparison between periods by evening out the highs and lows in business activity.You can do thi...
Population switching was found also as a crucial factor to explain volatility clustering and fat tails. On the other hand, the concept of a volatility series was introduced in [2] to study the volatility clusters in the S&P500 series. Moreover, it was shown that the higher the self-...
The variance inflation factor (VIF = 1/(1−R2)) and the condition index were used to test the collinearity. All assumption was evaluated for multiple regression model. Statistical analyzes were performed using IBM SPSS Statistics, version 23.0 (IBM Corp., Armonk, New York, NY, USA) and R...
