it fixes the issue The reason this is happening is that October 1 is in week 39 of 2017 but not in week 39 of 2018, so you're getting a -100% YoY change from the group ISOWeek 39 & October, which you're filtering out via the visual level filter on you measure' values. code :

## In 10. power / calculation / Power calculations

To fix this issue If you mean in XCode, you have to #include and then you can use pow:
code :
``````double res=pow(10, 1.5);
``````

## Sample size and power calculation in r as viable alternative to proc power in SAS?

I hope this helps you . In pwr.t.test and its derivatives, d is not the null difference (that's assumed to be zero), but the effect size/hypothesized difference between the two populations. If the difference between population means is zero, no sample size will let you detect a nonexistent difference.
If population A has a proportion of 15% and population B has a proportion of 30%, then you use the function pwr::ES.h to calculate the effect size and do a test of proportions like:
code :
``````> pwr.2p.test(h=ES.h(0.30,0.15),power=0.80,sig.level=0.05)

Difference of proportion power calculation for binomial distribution (arcsine transformation)

h = 0.3638807
n = 118.5547
sig.level = 0.05
power = 0.8
alternative = two.sided

NOTE: same sample sizes

> pwr.chisq.test(w=ES.w1(0.3,0.15),df=1,sig.level=0.05,power=0.80)

Chi squared power calculation

w = 0.2738613
N = 104.6515
df = 1
sig.level = 0.05
power = 0.8

NOTE: N is the number of observations

## Diagram that compares the power of the t-Test with the power of the Chi-sqare-Test

help you fix your problem If I understand the problem right, you are testing for a Binomial distribution with the mean under the null equal to 0.2 and the alternative being null greater than 0.2? If so, then on line 2 of you function g, shouldn't it be sigma <- sqrt(.2*(1-.2)) instead of sigma <- sqrt(.5*(1-.5))? That way, your standard deviation will be smaller, resulting in a larger test statistic and hence smaller p-value leading to higher power.

## Mixed Diagram (Line/Bar) with two y-Axis won't display data on 2nd Axis

it should still fix some issue Chart.js lets you add a line to a bar chart, but not a bar to a line chart. So you need to set the chart type to bar, e.g.:
code :
``````var config = {
type: 'line', // <-- change to 'bar'!
...
``````

Does that help I have selected Line and stacked column chart and configured Y-axis then changed ribbon chart not it showing as below.
