#How to find sigma symbol in word how to#
I actually figured out how to get the bias question actually (I believe it is $-\sigma^2/n$). Is this the correct approach? I am quite confused on how to go from here if it is correct? Help on the variance would also be greatly appreciated! Thanks so much :) EDIT: We know that the ML estimator of $\sigma^2$ is $\hat\sigma^2 = X/n$ where $X = \sum_)$$ To insert a special character: From the Insert tab, click Symbol. In the font box, choose the font you are using, click the symbol you want to insert, and select Insert. If the symbol is not in the list, click More Symbols. Unicode in Microsoft Word, type the four-letter code, then press Alt+X. Choose the symbol that you want from the drop-down list. numeric keypad, then select the character and change to the Symbol font U. We want to estimate $\sigma^2$ from a sample of size $n>2$ when $\mu$ is also unknown. To insert a symbol: From the Insert tab, click Symbol. Or look below to find out how to type sum symbol with keyboard using different techniques. Click on a Sigma symbol below to copy it out to clipboard automatically. Sigma is one of the most popular mathematic signs which means a summation of something. In the Font box scroll down until you see the font name Symbol. The sigma summation symbol is known by most as a mathematical symbol that indicades the sum. Let $Y_1.Y_n$ be independent normal R.V.s each with mean $\mu$ and variance $\sigma^2$. Click on the Division symbol (or click on More Symbols if it is not there) The Division symbol will now appear on the page.

Macro codes are big time savers and if a code can insert a delta symbol in a cell for you then there is nothing like that. VBA Code to Insert Delta Symbol to Multiple Cells. Cons: If you want to add a delta symbol to a cell for real then this method is not for you. I will first state the question I am trying to solve then I will demonstrate my thoughts! Pros: This is the best method in all the methods we have here because it doesn’t affect the values of the cell.
