This is the summary conclusion from our post:<br /><br />"The three critiques/suggestions offered by Dr. Underwood are not logically consistent with themselves, since they make contradictory assumptions about whether PIKE corrects for elephant populations/surveyor effort and whether or not the total count of carcasses discovered at each site is actually a random variable or not. Furthermore, each of the three points raised is itself independently erroneous, either because the mathematical assumptions Dr. Underwood makes cannot possibly be true (in the case of 2 and 3) or because these assumptions are clearly overturned by the data (in the case of 1). We therefore conclude that none of the critiques offered by Dr. Underwood are valid."Solomon Hsianghttp://www.blogger.com/profile/00936469103707728475noreply@blogger.comtag:blogger.com,1999:blog-3813701770708442620.post-28682424808992001572016-08-30T05:01:48.896-07:002016-08-30T05:01:48.896-07:00Hello
This blog post http://www.fmunderwood.com/20...Hello<br />This blog post http://www.fmunderwood.com/2016/08/30/understanding-hsiang-sekars-analysis/ and a report that this links to, describe the main reason why your analysis is so different to other analyses of MIKE data. It is not because of smoothing as you claim here, it is because your analysis does not account for the fact that the number of carcasses found varies hugely between sites and over time. R code to follow.<br />Thanks<br />Fiona Underwoodhttp://www.fmunderwood.comnoreply@blogger.com
