The R function t.test() can be used to perform both one and two sample t-tests on vectors of data. The function contains a variety of options and can be called as follows: > t.test(x, y = NULL, alternative = c("two.sided", "less", "greater"), mu = 0, paired = FALSE, var.equal = FALSE, conf.level = 0.95) Here x is a numeric vector of data values and y is an optional numeric vector of data values...

antibody detection is the most versatile and commonly used method for measles diagnosis. detection of specific igm antibodies in a single serum specimen collected within the appropriate time after rash onset can provide a good presumptive diagnosis of current or recent measles infection and is the test of choice for rapid diagnosis of measles cases. so, optimal timing for collection of a single...
Here x is a numeric vector of data values and y is an optional numeric vector of data values. If y is excluded, the function performs a one-sample t-test on the data contained in x, if it is included it performs a two-sample t-tests using both x and y. The option mu provides a number indicating the true value of the mean (or difference in means if you are performing a two sample test) under the...
چکیده مقدمه: در ناحیه دهان و فک و صورت عوامل گوناگونی از جمله تروما و پاتولوژی ها می توانند منجر به از دست رفتن بافت های موضع شوند. در این موارد ممکن است نیاز به بازسازی نواقص ایجاد شده در کف دهان، زبان، کام، استخوان آلوئولار و یا نواحی از اوروفارنکس باشد که برای این منظور از روش های مختلفی می توان استفاده نمود. یکی از شایعترین روش های بازسازی استفاده از انواع فلپ های عضلانی- مخاطی مانند فلپ ه...
The Verbal Paired Associates (VPA) subtest from the Wechsler Memory Scale-III (WMS-III) is one of the most widely used instruments for assessing explicit episodic memory performance. The normative data for the VPA subtest in the WMS-III manual show clear evidence of performance ceiling effects that limit the usefulness of this instrument. For this reason, we developed a new 15-item VPA test and...
OBJECTIVE To adapt a pre-existing educational game, making it specific to the teaching of blood pressure auscultatory measurement, and to apply this game in a pilot study. METHOD The original game cards were altered by the authors and submitted to content validation by six experts in the field. After redesigns, the game was applied to 30 subjects, who answered a questionnaire (pre-test and po...
Purpose To compare the lesion sizes of choroidal neovascularization (CNV) imaged with spectral-domain (SD) and swept-source (SS) optical coherence tomography angiography (OCTA) and measured using an automated detection algorithm. Methods Patients diagnosed with CNV were imaged by SD-OCTA and SS-OCTA systems using 3 × 3-mm and 6 × 6-mm scans. The complex optical microangiography (OMAGC) algori...
