statistics - Obtaining the Standard Error of Weighted Data in SPSS -


i'm trying find confidence intervals means of various variables in database using spss, , i've run spot of trouble.

the data weighted, because each of people surveyed represents different portion of overall population. example, 1 young man in our sample might represent 28000 young men in general population. problem spss seems think young man's database entries each represent 28000 measurements when represent one, , makes spss think have more data do. result spss giving very low standard error estimates , very narrow confidence intervals.

i've tried fixing dividing every weight value mean weight. gives plausible figures , average weight of 1, i'm not sure resulting numbers correct.

is approach sound? if not, should try?

i've been using explore command find mean , standard error (among other things), in case matters.

you need scale weights actual sample size, procedures in complex samples option designed account sampling weights properly. regular weight variable in statistics treated frequency weight.

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod...

ios - Change Storyboard View using Seague -

i have following code checks connection server, , depending on want change views if no connection found. nsstring *connect = [nsstring stringwithcontentsofurl:[nsurl urlwithstring:@"http://myserver.com"] encoding:nsutf8stringencoding error:nil]; if (connect == null) { [self performseguewithidentifier:@"network_failure" sender:self]; } else { // other code here } my problem not change views. have added storyboard segue between 2 views identifier of network_failure . not have navigation controller or that, problem? thanks help! no not problem. first of all, in objectivec exists nil object oriented null . must use that. so: if(connect == nil) or better: if(!connect) so due fact nil not same of null , probably code does't enter in if scope . you have been able discover breakpoint. anyway: be sure set trigger segue (line) 2 view controller , , name network_failure (that not best name. should instead view1toview2 ) as, m...
