However, the latest results from the Multimodal Treatment Study of Children with ADHD, the largest investigation of the benefits of medication against behavioral therapy, found that stimulants' effects wane over time. In addition, the study found that more than 60 percent of the children on stimulants stopped taking the medication within eight years.

The Facebook News Feed: How it Works,10 Biggest Secrets

Tom Weber conducts a one-month experiment to break the algorithm, discovering 10 of Facebook’s biggest secrets. The more digital our daily lives become, the more perplexing the questions seem. Will the growth of social media destroy our notions of privacy? Is democracy helped or harmed by the cacophony of opinions online? And perhaps most confounding: Why does that guy I barely know from the 10th grade keep showing up in my Facebook feed? If you've ever spent time on Facebook, you've probably pondered that last one.

Focus on the Threshold setting. The threshold is the maximum amount of volume that the Compressor will tolerate. The threshold is measured in decibels (db). Any bit of audio that is louder than the threshold has its volume reduced. You should set a threshold somewhere between the loudest and softest parts of your audio. Next, look at the Ratio setting. Leave the Attack Time setting as it is. Also, leave the Apply Gain after compressing option checked. Click the Preview button to test whether or not you chose the right settings.

It will calculate the Yates-corrected chi-square, the Mantel-Haenszel chi-square, the Fisher Exact Test, and other indices relevant to various special kinds of 2-by-2 tables: analysis of risk factors for unfavorable outcomes (odds ratio, relative risk, difference in proportions, absolute and relative reduction in risk, number needed to treat) analysis of the effectiveness of a diagnostic criterion for some condition (sensitivity, specificity, pos & neg predictive values, pos & neg likelihood ratios, diagnostic and error odds ratios) measures of inter-rater reliability (% correct or consistent, mis-classification rate, kappa, Forbes' NMI) other measures of association (contingency coefficient, Cramer's phi coefficient, Yule's Q) Enter numbers into the four cells below.
