Do the observations on (X , Y) follow the same linear model which is followed by the variables X & Y ?

We have two variables X and Y following the linear model Y = a + bX where a & b are the parameters. We have collected the pairs of numerical observations...

Is it possible to determine the actual values of the parameters, from a set of observations on (X , Y), following linear model ?

Suppose, we have the pairs of numerical observations namely (X1 , Y1) , (X2 , Y2) , (X3 , Y3) , ................... , (Xn , Yn) on the variables X and Y. Here the observations follow the...

Does there exist test statistic for testing of the significance of difference between the kurtosis of the two samples ?

I have two independent random samples . The distribution of data in each of the two samples may not be normal (mesokurtic) . Moreover, the kurtosis may not be same in the two data sets of the two...

Can the coefficient of correlation defined by Kearl Pearson be a proper measure of the degree of linear correlation between two variables ?

The coefficient of correlation r(X , Y) between two variables X and Y, due to Kearl Pearson defined by r(X , Y) = Covariance (X , Y)/{SD(X).SD(Y)} , measures the degree of linearity of...

Do two variables not remain as variables but become constants if the correlation coefficient between them is zero ?

The regression equation of Y on X is of the form Y = a + b X where b is the regression coefficient coefficient of Y on X. Similarly, the regression equation of X on Y is of the...

Is there necessity of framing of a definition of statistical equality (i.e. equality in statistical sense) ?

Suppose there are 5 samples having different means (sample means). Statistical testing of hypothesis may lead to the result that the 5 sample means are equal. It is clear that the 5 sample means...

Does there exist some measure of dispersion based on the deviations of all pairs of values in the data set which is better than standard deviation ?

Standard deviation, which is the most widely used measure of dispersion of data, is not based on the deviations of all pairs of values in the data set. A measure of dispersion based on the...
