Here is a certain predefined set of procedure to calculate the expected return formula for a portfolio. The coefficient of kurtosis, or simply kurtosis, measures the peakedness of a distribution.High kurtosis means that values close to the mean are relatively more frequent and extreme values (very far from the mean) are also relatively more frequent. The variance for a portfolio consisting of two assets is calculated using the following formula: Where: wi – the weight of the ith asset. You can easily calculate kurtosis in Excel using the Descriptive Statistics Calculator.. Coefficient of Kurtosis. The goal of a linear regression problem is to predict the value of a numeric variable based on the values of one or more numeric predictor variables.
