Abstract:
This study utilized two conversational speech databases to generate statistics about the frequency of occurrence of schwa deletion. Overall, the results showed a low frequency of schwa deletion in conversational American English. We investigated a number of factors that could have a potential effect on the propensity to delete schwa. The most pervasive factor was stress environment (pre-stress vs. post-stress), which showed a greater frequency of schwa deletion in the post-stress environment. The results are discussed with reference to processing spoken words and the role for corpus statistics in constraining models of word recognition.

Truncation in Survival Analysis
Left truncation occurs when individuals who experienced the event of interest before a certain time are not included in the study. This is often due to a "delayed entry" into the study where only those who survive until a certain entry point are observed.
Determination of Expected Frequency
Testing a Claim about Mean: Unknown Population SD
Estimating a population mean requires the samples to be approximately normally distributed. The data should be collected from the randomly selected samples having no sampling bias. There is no specific requirement for sample size. But if the sample size is less than 30, and we don't know the population standard deviation, a different approach is used; instead...
