The Omega Ratio is the probability-weighted gains divided by the probability-weighted losses after a threshold. You need to calculate the first-order lower partial moments of the returns data. This sounds difficult but it's very easy.
A spreadsheet to implement this formula can be found at the related link below
If the cell range "returns" contain the investment returns, and the cell "threshold" contains the threshold return, then the Omega Ratio is
={sum(if(returns > threshold, returns - threshold,"")) / -sum(if(returns < threshold, returns - threshold, ""))}

The Sortino Ratio is the actual return minus the target return, all divided by the downside risk. The downside risk is either calculated by the semi standard deviation, or the 2nd order lower partial moment. The related link "Calculate the Sortino Ratio with Excel" provideds an Excel spreadsheet to calculate the Sortino Ratio
calculate the effective return (mean return minus the risk free rate) divided by the beta. the excel spreadsheet in the related link has an example.
No. It can be but need not be. For example, you might calculate the ratio of today's temperature in Celsius and in Fahrenheit and calculate the ratio. That is not a rate.

Examine the related link. There's a guide to calculating the Sortino Ratio in Excel. There are several ways of calculating the downside risk in the Sortino Ratio - either the semi-deviation, or the square root of the 2nd order lower partial moment. When comparing the Sortino Ratio from several sources, make sure you use consistent values

The portfolio with the highest Sharpe ratio is on the efficient frontier, according CAPM. The Excel spreadsheet at the related link allows you to calculate a Sharpe optimal portfolio
Formula to calculate the ratio
Out = In / (1 + 2 s csi / omega + ( s / omega )2) where s is Laplace variable [s/rad] csi is the damping factor omega is the resonating frequency If you want to calculate the Vout/Vin ratio: ----L---- | C | ---------- csi = 0 (damping comes from resistive component) omega = 1/sqrt(LC)
At this time there is no official RDA for both omega 3 and omega 6.Experts agree however that one should be getting a minimum of 500mg of omega 3 daily, especially in the form of EPA and DHA, however 1 g is what most are leaning more towards.In terms of omega 6, the answer is not how much we should consume, but in order to make that fat beneficial it has to be consumed in a proper ratio with the omega 3.The best ratio for health has been listed as 3 parts omega 6: 1 part omega 3. Some other experts waiver anywhere between a 1:1 ratio to a 4:1 ratio.
