i want conduct theoretical chi square goodness of fit test: actual <- c(20,80) expected <- c(10,90) chisq.test(expected,actual) sample size n=100, alpha=0.05, df=1. gives critical chi value of 3.84. hand can calculate test statistic ((20-10)^2)/10 + ((80-90)^2)/90 = 100/9 > 3.84 however, above code yields pearson's chi-squared test yates' continuity correction data: expected , actual x-squared = 0, df = 1, p-value = 1 where mistake? i don't think you're testing intend on testing. @ ?chisq.test states, yates' continuity correction via correct= argument is: " a logical indicating whether apply continuity correction when computing test statistic 2 2 tables ." instead, try: chisq.test(x=actual,p=prop.table(expected)) # chi-squared test given probabilities # #data: actual #x-squared = 11.1111, df = 1, p-value = 0.0008581 you use optim find right values give chi-square statistic above critical value: crit...

i able implement map in fragment tab on android without flicker , after implementing click handlers action bar initiates dialog fragment datepicker , map flickers , overlaps action bar . might possible cos of error ? as can see above , map overlapping date picker dialog after flicker , , after touch datepicker dialog , map goes in background. similar problem happens action bar , i.e upon flicker action bar becomes transparent , map visible , runs fine ps: implementing googlemapv2 what can possible cause such flicker , overlapping issues? in advance , hint appreciated .

i'm trying reduce of configuration of our web application , have noticed our views.properties file has lot of redundant values can calculated programmatically. for example: welcome.(class)=org.springframework.web.servlet.view.tiles2.tilesview welcome.url=welcome home.(class)=org.springframework.web.servlet.view.tiles2.tilesview home.url=home login.(class)=org.springframework.web.servlet.view.tiles2.tilesview login.url=login is there way entirely without views.properties file (i'd rather more opinionated "file names must match view names" error-prone "updated these x config files") thanks time! so have been using hack rid of lame views.properties file 6 years now. here amazing solution of laugh at/use: define viewresolver way instead <bean id="viewresolver" class="com.yourcompany.util.tilesresourcebundleviewresolver"/> here implementation of resolver looks directly @ tiles views package com.yourcompan...

i interested in question when , if gwt garbage collection triggered in following example. i have composite: class extends composite implements hasclickhandlers { ... focuspanel panel = new focuspanel(); @override public handlerregistration addclickhandler(clickhandler handler) { return focuspanel.addclickhandler(handler); } } in view class create widget add click handler , add widget panel: a widget = new a(); widget.addclickhandler(someclickhandler); somepanel.add(widget); at point in application clear panel have entered widget. widget not attached dom anymore , there no reference pointing on widget. void removeall() { somepanel.clear(); } what happens widget , click handler. gwt garbage collection takes care of it? have save handler registration , remove click handler myself? one of advantages widget system manages of these memory issues you. provided combined widgets adding them other widgets (and never use getelement().appe...
