Bartlett test

Bartlett Test for iOS

BartlettTest
English
Bartlett test is one of the important statistical procedures pior to the comparison of avarages of more than two groups. This reveals the homogeneity of the variances of the groups. If significant (P is smaller than 0.05), the variances are not homogenous, then Kruskal Wallis test / Friedman test will be used to cpmpare the averages. If not-significant, one-way analysis of variance (one-way ANOVA) test will be used.





Chi Square test

Chi Square Test for iOS

ChiSquare
Statistical tool for researchers, students, doctors, etc. Test for independence for 2xn contingency table. Chi-square test with automatic selected Yates' correction for continuity and Wilcoxon rank-sum test are provided. For 2x2 table data, Fisher's exact probability is also provided.
When the levels are ordinal, refer to the results of Wilcoxon rank-sum test. Test for the effect of factors, such as dose-response. It is often used for the matched pairs data, for example, before and after data





EpidemRisk

EpidemRisk for iOS

EpidemRisk
A tool of statistics. Designed for scientists, doctors, teachers, students, journalists,etc. Test for the Odds Ratio and the Relative Risk, for 2 x 2 contingency table. Fill the cells with integers, then click "Calculate" button. You will see the ratio with confidence intervals. This is an easy statistical tool to use.

SmirnovTest for iOS

Kolmogorov-Smirnov Test
A tool of statistics. Designed for scientists, doctors, teachers, students, journalists,etc. Kolmogorov-Smirnov Test (K-S test) for an extreme element in the data. If significant statistically, the single extreme element may be rejected from the data.
This is an easy statistical tool to use.

McNemarTest

McNemarTest for iOS

McNemar
A tool of statistics for scientists, doctors, researchers, teachers, students, etc. This App contains both McNemar's test and Binominal exact test. For dichotomy paired data in statistics, McNemar's test is a non-parametric method to determine whether the row and column marginal frequencies are equal. McNemar's test is for comparison of proportions of paired data. When the row and column marginal samples are small, binominal exact probability is calculated in this App. This binominal statistic value is more reliable than McNemar's test in small number of cases. If the sample number is large enough (>25 in this App), binominal exact test is not necessary.




Paired t-test

PairedT for iOS

PairedT
A tool of statistics for scientists, doctors, researchers, students, etc.
This App compare the averages of two related groups. The difference is tested. You input the subtracted number list onto the input field, then touch calculate button. The statistical results are displayed.






Unpaired t-test

unpaired t test

unpaired t test

UnpairedT
A tool of statistics for scientists, doctors, researchers, students, etc.
This App handles unpaired t-test and Welch's t-test, that are automatically selected by variance comparison test. The confidence intervals of the difference of two averages are also provided.

This is a useful test for the comparison of mean for two independent groups.
At first, the variance (=standard deviation^2 = SD^2) of the data are tested. If the variance of the groups are not different, t-test (Student t-test) is applied automatically. If different, Welch's t-test is applied. When P value is less than 0.05, the averages of two groups are different. When P value is equal or more than 0.05, the averages are not different. If you like to know the confidence intervals of the mean difference, adjust the control bar. By default, variance criteria = 0.1, confidence interval=0.95. The total number of elements should not be over 100 elements.




one-way analysis of variance test (ANOVA)

ANOVA for iOS

ANOVA
You can compare the averages of multiple groups.
The one-way analysis of variance (one-way) ANOVA tests the null hypothesis that samples in two or more groups are drawn from the same population. This App is useful for researchers, doctors, teachers, students, financial analysts, etc.
Before you like to use this analysis, you need to make sure that the variances of the groups are not different using Bartlett test. "BartlettTest" is also for sale in iTunes App Store.

realJapan

real Japan for iOS

realJapan

We can think of our lives, as time goes, through our daily events such as marriage, birth, death, and so on, provided by the Japanese ministry of health, labor, and welfare. The budget of the Japanese government with relationship with our taxes makes us think of our lives. This data is also officially provided by the ministry of the internal affairs and communications.
Clocks for under_second, second, minute, hour, day, and year have been added. Data have been updated by the official release of Japanese government in 2012.
This is a universal app (available for both iPhone/iPod touch and iPad) 婚姻数、離婚数、出生数、死亡数、国家税収など、日本人の生活について元旦からの累計を1秒毎に表示していきます。データは政府公式データ(厚生労働省、財務省)に基づいて推定値を計算しています。
眺めていると、生活の一秒の重みを感じてきます。ご覧になる方の感性と知性で、受け取り方が様々です。政府からの各数値の発表ごとに更新しています。
iOS 7に対応しました。iPnone/iPod touchでもiPadでも利用可能です。
iOS 6 までは時を示す「1周で1秒の針」「秒針」「分針」「時針」「日針」「年針」を表示していましたが、ユーザーreviewのご意見にしたがい iOS 7からこれらは削除しました。



realUniverse

real Universe for iOS

real Universe for iOS

realUniverse
We can think of our lives, through our planet, our solar system, and the universe by seeing the number of movement of these as well as light travels.
Lorentz transformation is now visualized. A clock on a high speed rocket is shown, comparing a conventional clock on the earth. The rocket speed can be changed from 0.00 % to 99.999% of the light speed. The faster the rocket, the slower the clock on it by observers on the earth.



EDClite

EDClite for iOS

EDClite
Pregnancy calendar.
Expected date of confinement (EDC) or due date should be determined by your doctor. The gestational weeks and days at 40W0D (280th day) is the EDC. Pregnancy lasts about 38W0D (266 days) since fertilization.
Then, the beginning of the last menstrual period is the basis of calculation as 0W0D.
But, the early stage of embryo size measured by ultrasound or the date of embryo transfer or the blastcyst transfer is more accurate.
The delivery is classified as abortion (-21W6D), preterm delivery (22W0D-36W6D), term delivery (37W0D-41W6D), postterm delivery(42W0D-).
NOTE; The gestational month counting system in Japan is different from others. Traditionally, the first 4 weeks (0W0D-3W6D) is counted as the 1st month in Japan, though zero month in other culture. The Japanese counting system is used when you run in Japanese laguage system (Settings->General->International->Language). The western system is used when you run in English laguage system.
The EDC input is available from Jan 01, 1904 to Jan 01, 2999.
