示例1: addDays
addDays(days: number): CustomDate {
var newDay = this.day + days;
var newMonth = this.month + Math.floor(newDay / 30);
newDay = newDay % 30;
var newYear = this.year + Math.floor(newMonth / 12);
return new CustomDate(newYear, newMonth, newDay);
}示例2: calculateStandardDeviation
static calculateStandardDeviation(samples: number[], mean) {
var deviation = 0;
// TODO: use reduce
samples.forEach(x => deviation += Math.pow(x - mean, 2));
deviation = deviation / (samples.length);
deviation = Math.sqrt(deviation);
return deviation;
}示例3:
this._printStringRow(this._metricNames.map(metricName => {
var samples = validSamples.map(measureValues => measureValues.values[metricName]);
var mean = Statistic.calculateMean(samples);
var cv = Statistic.calculateCoefficientOfVariation(samples, mean);
var formattedMean = ConsoleReporter._formatNum(mean)
// Note: Don't use the unicode character for +- as it might cause
// hickups for consoles...
return NumberWrapper.isNaN(cv) ?
formattedMean :
`${formattedMean}+-${Math.floor(cv)}%`;
}));示例4: calculateRegressionSlope
static calculateRegressionSlope(xValues: number[], xMean: number, yValues: number[],
yMean: number) {
// See http://en.wikipedia.org/wiki/Simple_linear_regression
var dividendSum = 0;
var divisorSum = 0;
for (var i = 0; i < xValues.length; i++) {
dividendSum += (xValues[i] - xMean) * (yValues[i] - yMean);
divisorSum += Math.pow(xValues[i] - xMean, 2);
}
return dividendSum / divisorSum;
}示例5:
samples.forEach(x => deviation += Math.pow(x - mean, 2));
