To this end, many students make the use of onlinestatistics assignment help services.:Remark: an estimator is said to be unbiased when we have $E[\hat{\theta}]=\theta$. For $k, \sigma0$, we have the following inequality:Main distributions Here are the main distributions to have in mind:Marginal density and cumulative distribution From the joint density probability function $f_{XY}$ , we haveConditional density The conditional density of $X$ with respect to $Y$, often noted $f_{X|Y}$, is defined as follows:Independence Two random variables $X$ and $Y$ are said to be independent if we have:Covariance We define the covariance of two random variables $X$ and $Y$, that we note $\sigma_{XY}^2$ or more commonly $\textrm{Cov}(X,Y)$, as follows:Correlation By noting $\sigma_X, \sigma_Y$ the standard deviations of $X$ and $Y$, we define the correlation between the random variables $X$ and $Y$, noted $\rho_{XY}$, as follows:Remark 1: we note her explanation for any random variables $X, Y$, we have $\rho_{XY}\in[-1,1]$..
