Sequential Analysis: (SPRT)

  Sequential Analysis: We seen that in NP theory of testing hypothesis or in the parametric test n is the sample size and is regarded as fixed and the value of α fixed , we minimize the value of β.  But in the sequential analysis theory invented by A Wald in sequential analysis n is the sample number is not fixed but the both values α and β are fixed as constant.

Examples on correlation and Spearman's Rank Correlation Coefficient.

 Examples on calculating correlation coefficient.  To calculating correlation coefficient: There are three methods of calculating r. i.    Actual Mean method. ii. Step Deviation Method. iii. Assumed Mean Method. We see the one by one methods The another method of calculating the correlation is Spearman's Rank Correlation. this is an another method of calculating the correlation coefficient in simple way than the  Karl Pearson’s  developed by Spearman's. in this method the correlation is calculated based on the rank of the observations.  the rank correlation coefficient between x and y is 0.2857 Regression Notes
